Durable BK7 Glass Penta Prism For Long-lasting Alignment In Optical Instruments

Durable BK7 Glass Penta Prism For Long-lasting Alignment In Optical Instruments

Material:‌

1.Made from ‌BK7 optical glass‌, a high-quality borosilicate crown glass with exceptional homogeneity and low thermal expansion.
2.Features ‌anti-reflective (AR) coatings‌ on critical surfaces to minimize light loss (up to 99.5% transmission) and reduce stray reflections‌

Properties:‌

1.High durability‌: Resists scratches, humidity, and chemical corrosion, ensuring longevity in harsh environments.
2.Precision angles‌: 45°-90°-45° design maintains beam deviation accuracy within ±3 arcseconds for stable alignment‌
3.Broadband compatibility‌: AR coatings optimized for visible to near-infrared spectra (350-2000nm).

Function:‌

1.Beam steering‌: Deviates incoming light at a fixed 90° angle without inverting the image, critical for laser systems and metrology tools.
2.Alignment stability‌: Maintains positional accuracy over time due to BK7’s low stress birefringence and robust mounting options.

Applications:‌

1.Laser systems‌: Used in interferometers, rangefinders, and fiber optic alignment for precise beam control.
2.Metrology‌: Essential in theodolites and autocollimators for industrial and astronomical measurements.
3.Defense/Aerospace‌: Deployed in targeting systems and periscopes due to shock resistance and reliability
