Laser alignment products reshape non-visible ultaviolet and infrared light particles into visible light. This is important to user safety when working with laser equipment.
Laser alignment products can pick up visible radiation, infrared radiation and ultra violet radiation and make them visible to the naked eye. These products have scintillator screens that are made of phosphor. They are mounted in non-reflective plastic housings....
What are laser alignment products used for?
Laser alignment products are used in industries where radiation levels need to be detected and monitored for operator safety. Such industries include nuclear plants and factories using radioactive chemicals like uranium and plutonium.
These products are also used in automotive and industrial environments for alignment purposes such as in bore equipment and lathe machinery.
Types of laser alignment products
Laser alignment products can be freestanding, disc mounted or screw mounted.
Laser wands are used in laboratories as they can be fixed onto lens tubes and testing equipment.
Laser cards are sized like credit cards and are portable which makes them useful for checking different laser beam paths.
Laser discs have screw ports which attach to surfaces and equipment for more permanent applications.
A laser detector is a passive device designed to detect infrared emissions. A laser pulse originates from a transmitter and channels to an object. The light particles (photons) are then scattered back from the object to the receiver. Laser detectors can survey the distance to a target by measuring the laser pulses reflected back from and object to the transmitter. Laser detectors are also called lidar detectors. They are cost-effective and are easier to operate than radar detectors....
What are laser detectors used for?
Laser detectors have a variety of applications. They are used for condition monitoring purposes in factories and plants, where smog, fog and particle detection is necessary. They are also commonly used in incident or event monitoring, to detect beam breaking in laser alarm systems, for example. Laser detectors are also important in the manufacturing industry where optical sensing and transmissive telemetry equipment require device monitoring and event detection mechanisms.Types of laser detectorsTypes of laser detectors include charge-coupled devices (CCD), complementary metal oxide semiconductors (CMOS), position-sensitive detectors (PSD), and photoelectric sensors. Laser detectors can operate on their own or simultaneously (two or more) within a particular machine component.
Laser diodes are semiconductor devices which closely resemble an LED (light emitting diode). How do they work?Laser diodes work in a very similar way to LEDs, however they create a laser beam at its junction instead. They create a very precise beam of light which is ideal for applications which require an accurate reading of data. They are also capable of a very powerful output, which can be determined by their optical output power.Laser diodes are available in a range of different packages, for example TO-38 and TO-56....
What colours are laser diodes?
The most common laser colours are red, blue and green. Their colour is described in wavelength, the same as an LED. Wavelength values are given in nanometers (nm). Red is around 660nm Blue is around 500nm Green around 550nm. Laser diodes are also available with infrared (IR) light. Where are laser diodes used? Fibre optic communications Barcode readers Laser pointers/pens Disc reading & recording Laser printing Laser hair removal devices
The function of a laser driver is to deliver the exact amount of current set, and at whatever voltage is needed, to the laser diode in a circuit. As a result, they protect the laser diode from damage. Laser driver applicationsLaser drivers are used in a variety of applications, such as:
Diagnostic and analytical equipment
In the medical field
Why does a diode need a laser current driver?
An often overlooked factor in using laser diodes in circuits is the influence of temperature on the output power and operating current. While the threshold current rises as the temperature increases, the optical output power and differential efficiency decrease. The driver circuit therefore needs a safety feature that ensures that a significant temperature increase will not destroy the laser – a laser driver fulfils this need.Laser drivers provide closed-loop control of the average optical power of a continuous wave (CW) laser diode. The control loop adjusts the laser to maintain a constant current and power. This ensures a regular temperature and so protects the laser from heat damage.
Laser lenses are designed to focus the beam of laser light onto the object. Lenses are used in a variety of applications and other the focusing light they can also change its shape. Lens can transform cylinder laser focus beam into: line, cross, ring Lenses can be pre-set to focus the light at desired distance for an example 100 mm or 300 mm and deliver exceptional results when are used with correct wavelengths....
. Installing and changing lenses is an extremely easy task as all lenses are fitted with a screw type mounting and it takes only a couple of seconds to fit a correct lens for a project.
Laser modules are packaged devices which contain a laser diode alongside other components, such as power control. They often have an aluminium body and cables to connect to power. Continuous wave lasers have a continuous output beam which remains constantly on, until they are switched off. It is used for fibre optics, laser printing and barcode reading....
Output Power, measured in mW, rates the power of the laser beam. Your choice of output power will vary depending on how powerful you require the laser to be. The colour of the laser output is called wavelength and is measured in nanometres (nm). Different wavelengths represent different colours.Where are they used? Laboratories Industrial applications Laser alignment Robotics Positioning systemsDifferent colours available: Blue Green Red
Laser mounts are used to secure a laser to an optical system. This makes laser system alignment easier and helps to remove unwanted movement. Laser mounts are usually adjustable and can therefore be moved up and down or around the system. They can also form part of the temperature control of a laser system, absorbing and managing the heat given out by the laser....
What are laser mounts used for?
As well as providing stability, laser mounts can contribute to temperature management in one of two ways:
Passively cooled laser mounts use a heat sink to conduct heat away from the laser and dissipate it.
Actively cooled laser mounts use an in-built Peltier cooler to cool one surface while heating another. The laser mount then acts as a heat sink for the Peltier device rather than the laser itself.
Types of laser mounts
Laser mounts mainly differ according to size, as they are designed to fit a specific type of laser. They are able to hold different diameters of laser head, or may be targeted to a particular brand.
Laser power supplies are devices used to provide electrical power to lasers. The main function of any power supply is to convert a given electric current to the correct current, voltage and frequency for the output device, which in this case would be the laser.
How do laser power supplies work?
A laser power supply takes the electrical current from a power source, and converts it into a form that the laser can use. Lasers need high voltage power supplies, but they also require a great deal of stability in the supply, as they are delicate devices. The light-emitting parts of the laser can be damaged by even a short pulse of excess current, and power supplies need to accommodate for this.
Types of laser power supplies
Simply put, laser power supplies come in battery or mains-powered forms. Battery-operated laser power supplies offer greater mobility than those attached to the mains electricity. However, mains power supplies can be plugged into an extension to offer extra mobility if needed, and are also able to power more than one laser at once.
