The 1550nm (S-Band, C-band, L-band, U-Band) Optical Isolator product line is designed for today’s wavelengths, beam sizes and power levels.  We offer 4 versions of 8mm aperture models.   Vacuum compatible models series 2117 &2120.  We offer series 2115 TEC Peltier cooled Optical isolators. The design features of the optic mounting insure reliable performance.  This region has many material and polarizer options allowing for OEM optimization we can offer special variations to fit your specific needs.
It is not possible to list all the possible design options for this region. Please contact us and we will quickly configure our designs for your wavelength of interest. Isolation values typically exceed 35 dB at the center wavelength. Our standard models include power handling levels and apertures unique to the market.

We off 45 degree angle of incidence polarizers PP45 series in 5mm and 8mm apertures.  Isolators are available with these polarizers.  These polarizers allow isolator to be used a free space circulator to eject Rs energy at 90 degrees.  By design these polarizer surfaces do not reflect energy back towards the laser as an added benefit.
