Product Description
Aluminized Outer Reflection BK7 Optical Glass 90 Degree Rectangular Prism Right Angle Prism
The design of the Aluminized Outer Reflection BK7 prism is optimized for systems where internal light absorption must be eliminated. Unlike standard prisms that rely on total internal reflection (TIR), this Right Angle Prism utilizes an Aluminized Outer Reflection coating to reflect light directly from the first surface it encounters. This is particularly beneficial for the Optical Glass 90 Degree Rectangular Prism in high-vibration environments, as the mechanical stability of the BK7 substrate is superior to thin-film mirrors. Furthermore, the Rectangular Prism geometry allows for easy mounting and integration into compact optical housings. Whether you are constructing a complex beam splitter or a simple path folder, the Aluminized Outer Reflection BK7 ensures that your Optical Glass 90 Degree path remains pristine and aberration-free.

Expert Product FAQ
Q1: Why choose an Aluminized Outer Reflection BK7 over a standard TIR prism?
Answer: The Aluminized Outer Reflection BK7 is preferred when you need a "front-surface" effect. Because it uses Outer Reflection, the light never enters the glass, which eliminates chromatic dispersion. This makes the Optical Glass 90 Degree Rectangular Prism more effective for broadband light sources.
Q2: How durable is the coating on the Aluminized Outer Reflection BK7?
Answer: Our Right Angle Prism features a protected aluminum layer. This means the Aluminized Outer Reflection surface is capped with a thin dielectric layer (like SiO₂), which protects the metal from oxidation and minor scratches during handling of the Optical Glass 90 Degree unit.
Q3: Can the Rectangular Prism be customized for specific wavelengths?
Answer: Absolutely. While the Aluminized Outer Reflection BK7 is great for general use, we can modify the Outer Reflection coating to silver or gold if your Optical Glass 90 Degree application requires higher reflectivity in the infrared spectrum.
Q4: What is the benefit of the BK7 material in an Outer Reflection prism?
Answer: Even though the light doesn't enter the glass in Outer Reflection, the BK7 substrate is vital because it is extremely stable. This ensures the Right Angle Prism angles do not warp, maintaining the Optical Glass 90 Degree precision over the product's lifetime.
Q5: How should I clean the Aluminized Outer Reflection surface?
Answer: You should treat the Aluminized Outer Reflection BK7 with care. Use an air duster to remove loose particles from the Optical Glass 90 Degree face, then gently wipe with a lint-free tissue and reagent-grade alcohol. Avoid excessive pressure on the Rectangular Prism reflective face.
