CVI PW-0512-UV Laser Grade Optical Window

The CVI PW-0512-UV is a precision plane-parallel optical window manufactured by CVI Laser Optics (now part of IDEX Optical Technologies). It’s designed for demanding optical and laser applications where high transmission in the ultraviolet (UV) spectrum and excellent optical quality are required.

📌 Key Details

• Type: Plane-parallel optical window (PW series)

• Material: UV-grade fused silica (UVFS) — excellent transmission in the ultraviolet range.

• Diameter: 12.7 mm (0.5 in) — standard small optic size.

• Thickness: ~3.18 mm — typical thickness for this part number.

• Surface Quality: High quality (e.g., 10-5 scratch-dig) and low transmitted wavefront distortion (λ/10), suitable for precision optical systems.

• Parallelism: Tight tolerance (≤5 arc min), meaning the two faces are very flat and parallel for minimal beam distortion.

🧰 Typical Uses

These UV optical windows are used to:

• Seal or isolate optical systems while letting light pass with minimal distortion

• Serve as viewing windows in laser or vacuum chambers

• Protect sensitive optics in UV laser paths

• Be integrated into setups requiring high transmission from deep UV through visible wavelengths
