World Star Tech's circular laser modules come in a compact package with integrated electronics and optics. The UL and UH series circular modules use microlens technology to produce clean, diffraction limited gaussian beams. They are particularly ideal for coupling to single and multimode fibers. They are available in a range of powers and wavelengths.
The CL and CH series laser modules are circular beams produced by the diode. They are available in 635nm only and upto 7 mW power.
.TTL or Analog modulation option is available.
