A G lobal Laser Bran d Varilite Alignment Kit Varilite Alignment Kit The Varilite PWM Development Kit provides a complete solution to a wide range of visual alignment applications, including positioning of garments, cloth, paper, wood and metal and a wide range of machine vision applications. Three versions of the kit are available in 635nm, 1mW & 5mW and 660nm 20mW. The kit is supplied in a robust case, comprises of a Varilite laser diode module, five interchangeable optics which produce a range of line and cross and pattern projections, a heavy duty mounting clamp for easy set up and adjustment and a 110V/240V voltage adaptor, including leads for UK, Euro and US main sockets. The Laser can produce either a elliptical dot or a projection when fitted with one of the supplied interchangeable optics. A user adjustable collimating lens allows the user to adjust the focus (size) of the beam at the desired working distance via a supplied key. Each of the five interchangeable optics are simply screwed into the end of the laser diode module to produces the required projection, which include a line, cross projection, multiple circles, multiple lines and a dot array. The laser can be either operated from a 110/240 adaptor supplied with the kit or from a 5Vdc supply. When used with a 5Vdc supply the optical output of the laser can be pulse width modulated from a TTL level input signal, within the limits of the laser modules maximum rise and fall time. You can therefore control the mean intensity of the laser beam simply by changing the mark to space ratio or modulate the laser with coded information or synchronised it with an external device such as a camera or photo detector. The heavy duty mounting clamp is also supplied which allows the Varilite to be securely fixed at any required direction or angle. The base plate has a series of threaded holes which allows the clamp to be fixed directly onto a machine or workbench. The Varilite has a threaded barrel to simplify bulkhead mounting and ensure a good thermal contact between the module and the mount thus assisting with a good heat dissipation. It represents the highest level of optical and electrical performance at an economical price, a combination that is unmatched in the marketplace. Varilite Key Features - 635nm 1mW, 5mW or 660nm 20mW - User adjustable focus - 5 interchangeable optics supplied including, Cross, Line, 7 Line, 5 Concentric Circles, 21x21 Dot Array. - Two year warranty - Heavy duty clamp allows the laser to be adjusted and securely fixed at any required direction or angle. - Power Supply 110/240 Vac to 5V DC with UK, Euro & US plug Accessories Heavy Duty Mounting Clamp The heavy duty mounting clamp allows the Varilite to be securely fixed at any required direction or angle.

The voltage adaptor is CE marked and also has a power on indicator. A 1 meter lead to connect the laser diode module to the adaptor is also supplied. Modulation A common requirement for applications which use photo detectors, cameras and other nonvisual sensing is the ability to rapidly switch the laser output ON and OFF. Simply applying and removing the supply voltage is rarely satisfactory and in certain cases can result in the destruction of the module. This is because laser diodes are very sensitive to spikes and surges, which are often the result of uncontrolled supply switching. To overcome this limitation, the VarIlite has two additional inputs that are provided to control the output of the laser module in a reliable and predictable way. These inputs can be used via a supplied four wire lead, the laser will need to be run from a regulated DC power supply with an output voltage of 5Vdc ±5% when used this way. Modulation Input A PWM input is available via the third wire logic LOW level turns the output completely OFF(=/
