Gratings

Grating is a dispersive element that uses the principle of light diffraction and interference to split light, and is widely used in spectrometers, spectrophotometers, etc. Dimension-Labs encoders offer planar scribe gratings, planar holographic gratings, transmissive gratings, stepped gratings, and more.

Transmissive gratings

Infrared aspherical lens

Peculiarity:

• No spherical aberration is introduced when focusing or collimating the beam

• Optional unmounted or mounted mount

• Reflection enhancement film: 1.8-3μm, 3-5μm, 8-12μm

Apply:

• For collimating light from shortwave infrared (SWIR), medium wave infrared (MWIR), and long-wave infrared (LWIR).

• Fiber optic coupling

• Imaging the beam on the detector, etc
