Optical glass half penta prism

custom penta prism

penta optical prism

penta angle prism coated

A high-precision half penta prism designed for accurate and stable beam deviation by 90°.

It features a critical reflective coating on its hypotenuse surface, making it an essential component for applications requiring precise optical path folding and alignment with minimal back-reflection.

Description

Factory custom Optical glass penta prism optical prism

Detailed Specifications:

Coating on Entry/Exit Faces: Optional Broadband Anti-Reflection (AR) Coating.
Laser Damage Threshold: Customizable based on coating selection (e.g., >5 J/cm² for 20ns pulse @ 1064nm for certain dielectric coatings).
Mounting: Optional black anodized aluminum housing with mounting holes.

Features & Benefits:

Precision Beam Steering: Provides a consistent 90° beam bend with high angular accuracy.
Dedicated Reflective Surface: The coated hypotenuse eliminates the need for total internal reflection, allowing use with unpolarized light and over a wider range of incident angles.
Customizable: Available in a wide range of sizes, materials, and coating specifications to meet exact system requirements.
Durable Construction: Made from high-grade optical glass with precision polish for long-term stability and reliability.
Reduced Ghost Images: Properly coated to minimize stray reflections.
