CVD ZnSe Reflective Neutral Density Filter | 50% Transmission @ 5000nm

CVD ZnSe Reflective Neutral Density Filter | 50% Transmission @ 5000nm

Engineered for precise mid-infrared beam intensity control, our CVD ZnSe reflective neutral density filter delivers consistent 50% transmission at 5000nm with a ±5% tolerance window. Fabricated from high-purity chemical vapor deposition zinc selenide, this optic maintains stable attenuation performance across the mid-IR spectrum with minimal spectral shift under typical operating temperatures. It is designed for seamless integration into demanding optical setups, pairing reliably with standard beam delivery components.

Technical Specifications

Typical Applications

This precision ZnSe attenuator serves a wide range of mid-infrared systems requiring controlled light intensity. Primary use cases include:

• FTIR spectroscopy and monochromator source intensity calibration

• Mid-IR laser beam power attenuation and regulation

• Infrared gas sensing and analytical detection systems

• Radiometric calibration and thermal imaging setups

• Industrial laser processing and material treatment systems

Customization & Service Support

We maintain an extensive in-stock selection of standard IR optics — including CVD ZnSe lenses, CVD ZnSe windows, and ZnSe prisms — for fast, reliable delivery, alongside this 5000nm ND filter. For project-specific requirements, we offer full customization covering custom dimensions, alternative transmission values, specialty coatings, and unique form factors. Every custom order undergoes a full engineering drawing review before quotation, and all production follows ISO 9001:2015 compliant processes with pre-shipment inspection to guarantee world-class precision and consistent lead times.
