Laser Diode Module, 940 nm, 90 mW, CW, Elliptical beam

laser diode module shown with protective cap

The LQC940-90E CW Laser Diode Module is an economical choice. It includes the diode and collimating optics in a single case. This Fabry-Perot (FP) 940 nm Laser Diode Module with a 90 mW CW elliptical beam comes in a self contained module. It requires a 5 VDC external power supply. An LPMS-5-110 or LPMS-5-220 Series Power Supply (not included) must be used with this LD module to meet CDRH requirements by providing an interlock input, key enable switch, delayed start-up, and laser active indicator. Warranty is not applicable when a custom power supply is used to drive the module.

LQC Series for Excellent Performance

The LQC Series includes a self-contained laser diode with superior optical quality, a very high precision current source and a PID temperature controller built in the module. These laser modules are ideal for demanding experimental setups where the temperature and current control are important.

Protective rubber cap included only with Class 3B lasers and above.

Elliptical or Circular Beam Output

All LPM and LQC diode lasers are available either in elliptical (E versions) or circular (C versions) output beam shape. Circular beams are generated using a micro lens built in the diode laser and exhibit better quality than elliptical versions. The wavelengths indicated are typical values only, due to the nature of FP lasers.

LPMS Power Supplies Recommended for Use with Laser Diode Modules

Newport's LPMS Series Power Supplies (sold separately) are more than just power supplies. This is a key instrument that will make the LPM and LQC laser diode modules CDRH-compliant. It provides an interlock input, key enable switch, delayed start-up, and laser active indicator. The laser modules in the wavelength range of 375-473 nm require an 8/12 VDC power source. Those in the range of 635-2330 nm require a 5 VDC power source. (Note: Warranty is not applicable when a custom power supply is used to drive the laser diode module.)
