Quartz Achromatic Quarter-Wave Plate AWP20Q-T3Q
Quarter-wave plates commonly convert linear and circular polarization into each other to control source polarization. Unlike standard plates, achromatic plates provide stable phase retardance over a broad wavelength band, unaffected by incident wavelength. JCOPTIX achromatic quarter-wave plates combine birefringent quartz and magnesium fluoride crystals with an air gap. The quartz fast axis aligns with the magnesium-fluoride slow axis, balancing and canceling relative retardance shifts across the band to leave a net quarter-wave retardance. Efficient broadband AR coatings on every surface ensure excellent transmitted wavefront quality and minimize beam deviation and reflection losses. Flat response particularly suits tunable lasers, multiline lasers, and broadband sources. The air gap raises the damage threshold for high-power use. JCOPTIX plates with 10 mm and 20 mm clear apertures have standard SM05 or SM1 external threads; 45 mm clear-aperture plates mount in externally threaded SM2 tubes. These fit matching internally threaded rotation mounts such as MMR-05T, MMR-1T, and MMR-2T. JCOPTIX's proprietary rubber washer at the external-thread base facilitates direct alignment to specific mount angles. Operation is simple and quick: 1. Screw the achromatic plate into the rotation mount until the SM05/SM1 thread reaches its end; lock the rotating part as needed. 2. Check the angular difference between the fast-axis direction (white housing line) and the target scale mark (0° or 90°). 3. Apply slight force to continue turning the protruding cylindrical part until the white fast-axis line aligns with the target mark. Adjustment is approximately 60°. JCOPTIX offers mounted achromatic plates with diameters of 10 mm and 20 mm, covering 400-700nm, 700-1100nm, and 1100-1650nm. Contact technical support for custom sizes, coatings, or bands.

Low-Order Waveplate WPL210 Waveplates Zcoptic
Retardance [Low-Order Waveplate; All Standard Products Use Quartz]: λ/2 Diameter [Low-Order Waveplate; All Standard Products Use Quartz]: 10.0 mm Standard Mount Diameter [Low-Order Waveplate; All Standard Products Use Quartz]: 25.4 mm
Multiple-order wave plates made from quartz or MgF2 are available; standard products are quartz. Any operating wavelength from 150-7000nm can be selected. Low-order wave plates consist of a single quartz or MgF2 crystal plate, using the optical path difference between the O and E rays to obtain the required phase retardance. Compared with zero-order wave plates, low-order wave plates have a simpler structure and lower cost, making them suitable for high-volume industrial applications. Their single-plate structure provides a high damage threshold. Features: single-plate construction; customizable wavelengths from 150-7000nm; antireflection coatings on all surfaces; high damage threshold; low price. Processing specifications: standard wavelengths of 266nm, 355nm, 532nm, 632.8nm, 780nm, 808nm, 980nm, 1064nm, 1310nm, and 1550nm. Standard low-order wave plates.

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
A laser bar is an array semiconductor laser chip integrated with dozens of emitters, which realizes hundred-watt quasi-continuous output on a single chip. With regular emitter arrangement and controllable fill factor, integrated thermal design and superior wall-plug efficiency compared to single chips, it acts as the core light source for high-power pumping, medical lasers and precision processing.
