High-precision customizable optical glass Dove prisms

BK7 and Fused Silica Glass Dove Prisms

Dove Prism are usually made of optical glass and have the simple shape of a right-angled triangular prism. Light is reflected twice inside the prism, rotating the image 180° without reversing it left to right. In optical systems, they are often used to change the optical path direction and adjust image orientation, and are widely used in instruments such as telescopes and microscopes to optimize imaging quality and optical path arrangement.

BK7 and Fused Silica Glass Roof Prisms

Roof prisms, also known as Amici prisms, are optical prisms that deflect the line of sight by 90° while erecting the image — reverting and inverting it to maintain the correct visual orientation. They are widely used in spotting scopes, binoculars, telescopes, and other optical instruments.

Measurement Prism and L-bar Mini Prism

Measuring prisms reflect light signals emitted by total stations and other instruments, assisting in distance measurement. With their precise optical design, they can extend the measurement range and improve accuracy, and are widely used in geodesy, engineering surveying, mapping, and other fields. L-bar prism is small and easy to carry, and its L-shaped design allows it to adapt flexibly to complex measurement environments, providing reliable support for accurate data acquisition in scenarios such as tunnel monitoring and building settlement observation.

High Purity Equilateral Prisms And Dispersive Prisms

High-quality Optical Glass Equilateral Prisms And Dispersive Prisms

Equilateral prisms have three equal 60° angles. Thanks to their geometry and optical properties, which separate light of different wavelengths, they are often used as dispersive prisms and are widely applied in spectral analysis and other fields. Dispersive prisms are usually triangular in cross-section. Because different wavelengths of light are refracted at different angles in the same material, they can decompose polychromatic light into monochromatic light, playing a key role in spectrometers, optical parametric oscillators, and other instruments.
