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.
Gratings
Reflective grating

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
