Newport 05RP02-40 Zero-Order Quartz Half Wave Plate 1550nm

OD: 12.7mm
CA: 8mm

Newport Description:
The 05RP02-40 is a (lambda)/2 Retardation Zero-Order Quartz Wave Plate, 12.7 mm in diameter and optimized for 1550 nm. Zero-order wave plates are temperature insensitive phase retarders for moderate bandwidth applications. These zero-order wave plates are constructed of two quartz plates, air-spaced to allow for use with high-power lasers, in a standard 12.7 mm or 25.4 mm diameter housing for easy mounting into a holder. Zero-order wave plates are moderately insensitive to wavelength change, which makes them ideal for laser diode or tunable laser applications. Typical zero-order wave plates have a temperature coefficient of 0.0001 (lambda)/degC.

Listing is for single optic with mount.

Optics For Research now Thorlabs IO-5-NIR Faraday Rotator for Free Space Optical Isolation

CA: 5mm Diameter @ 1.5″ from Base
Wavelength: 750-900nm

This used OFR IO-5-NIR Faraday Rotator came from a working environment but has not been tested. Please call us for more information.

From manufacturer website: Optical isolators are magneto-optic devices that only transmit light in one direction. They are able to isolate a source, such as a laser, from back reflections. Back reflections typically create instabilities in a system, which can lead to a number of issues. Mode hop, amplitude modulation, and frequency shifts are all possible side effects of these instabilities. Additionally, power spikes created by back reflections can permanently damage equipment such as lasers and optics..
