Model 1144, 15mW Random Polarization, Lumentum HeNe Laser

Product Details 110V or 220V power supplies sold separately. These HeNe lasers comply with 21CFR1040 and IEC 825-1:1993. Power Options from 0.5 – 22.5mW Improved Stability Ideal for Interferometry and Metrology Applications Random or Linear Polarization Options Lumentum High Performance Helium-Neon Lasers feature a patented close-cathode design that provides improved thermal and power stability. They also utilize a patented field concentrator design that enables fast turn-on. These Lumentum HeNe lasers also feature precisely aligned cylindrical housings, with cylindrical laser heads and electrical interconnect systems used to simplify system integration. Lumentum High Performance Helium-Neon Lasers’ rugged design is ideal for even the most demanding applications. They are exemplary for use within interferometry and metrology applications. Note: Please exercise caution when using a user-provided power supply to not exceed the electrical specifications of the laser as this may cause damage and void the warranty. These HeNe lasers comply with 21CFR1040 and IEC 825-1:1993. Lumentum was previously known as JDSU.
