Optical Devices

Optosigma Optical Devices are passive optical components for laser beam manipulation, polarization control, intensity modulation, and fiber coupling in photonics laboratories.

Polarization components:
– Wire-grid polarizers: broadband UV to NIR; high extinction ratio (over 1000:1)
– Glan-Taylor and Glan-Laser prism polarizers: high power handling; extinction over 100000:1
– Zero-order waveplates (quarter-wave and half-wave): low temperature sensitivity; for 355-1550 nm
– Achromatic waveplates: constant retardation over broad bandwidth; for tunable laser systems

Beamsplitters:
– Plate beamsplitters: non-polarizing 50:50 and ratio splits; broadband AR coated
– Polarizing beamsplitter cubes: high extinction; for PBS-based interferometers
– Cube beamsplitters: compact; multiple split ratios from 10:90 to 50:50

Neutral density filters:
– Absorptive ND: OD 0.1 to 4.0; uniform attenuation 200 nm to 2500 nm
– Reflective ND: for high-power lasers; reflects rather than absorbs
– Variable ND wheel: continuously variable OD 0 to 4

Other components:
– Optical choppers: rotating wheel; 1 to 10000 Hz chopping frequency for lock-in detection
– Spatial filters: pinhole and objective assembly for beam cleaning
– Fiber-optic couplers and collimators: FC/PC and SMA; 400-1700 nm
