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
