Product Overview

By applying dielectric coating only — instead of a hybrid metallic coating — CeNing Optics' non-polarizing beamsplitter cubes achieve negligible energy loss. Transmittance and reflectance can be precisely controlled to 50%, giving consistent, predictable beam splitting performance.

Key Features

• Design uses dielectric coating only, with no hybrid metallic layer
• Energy loss is negligible
• Transmission of P-pol and S-pol is very close to 50%, within ±2%

Highlight Specifications

• Substrate material: N-BK7
• Beam deviation: 3 arc min; surface quality: 60-40 S/D
• Surface flatness: λ/4 @ 632.8nm; clear aperture: >90%
• Coating: dielectric partial reflective coating on the hypotenuse, AR coating on entrance and exit faces
• Available for narrow wavelength ranges only
