The 5002-47-000 is a Versatile Laser Module with an isolated housing and reverse polarity protection as standard. An A/R coated user adjustable collimating lens produces an elliptical output beam which can be focussed to produce fine spots. A TTL enable input is also included as standard which allow the user to switch the laser on and off with a TTL logic level signal. Further versatility is provided by the wide range of external optics available which simply screws into the end of the laser module, allowing the user to quickly and efficiently switch from one projection to another. The range includes Homogeneous lines and cross's and diffractive patterns.
