HeNe Laser, Red, 633 nm, 687 MHz, 2.0 mW, 500:1 Polarization, CE
Model: N-LHP-121
Product Series Overview
Red HeNe Lasers - 633 nmThe N-LHP-121 HeNe Laser generates a 500:1 linearly polarized output of 2.0 mW (minimum) at 633 nm. Longitudinal mode spacing is approximately 687 MHz with the spectral bandwidth being approximately 1400 MHz (FWHM). This CE compliant, IEC Class 3R red HeNe laser offers TEM00 mode at 633 nm. The power supply is included. A spare or replacement laser head and power supply can be purchased separately off-line. The laser head model is N-LHP-121-H, and the power supply model is N7-LPL-911-065.
HeNe Laser Mounting
ULM Series cylindrical laser mounts attach to 340-RC and 370-RC rod clamps and provide a convenient way to attach these HeNe lasers to Newport stages, tables, or breadboards. For N-LHP and N-LHR series, please mount the laser at either end of the body indicated by shading.
Random or 500:1 Polarization
We have models whose outputs are either polarized or randomly polarized. Due to the random fluctuation of the polarization state of the beam, it is not recommended to use a polarizer with a random polarization laser for applications where polarized light is required. The laser with the polarized output has a vertical polarization direction, when the shutter control is shown at the top.
