Prism
Right-angle prism
Right-angle prisms are typically used to deflect optical paths or turn light rays by 90°. Utilizing the critical angle characteristic to achieve total internal reflection of incident light is one of their basic functions. With easy installation, excellent mechanical stress stability and strength, right-angle prisms are ideal optical components for various devices and instruments.

Ridge Prism
The roof prism simultaneously inverts and reverses the image plane while enabling a 90° deflection of the optical path. Its compact design allows the objective lens and eyepiece to be arranged in a straight line, making it ideal for compact binoculars, spotting scopes, and other such devices.
Powell Prism
The Powell prism, functioning as a line laser generator, projects a uniform linear reference line, making it ideal for applications such as alignment and positioning, machine vision systems, construction work, and process control. Additionally, this prism can be used with low-power lasers, offering customizable models with a wide range of divergence angles—5°, 7°, 10°, 30°, 45°, 60°, 75°, 90°, and 100°—to meet the line laser generation needs across all wavelength ranges.

CNI We can provide a wide range of custom roof prism products tailored to customer needs. Optical filters are optical components designed to transmit light at specific wavelengths while reflecting or attenuating light outside those wavelengths. They offer several key advantages: high peak transmittance, a flat passband spectrum, excellent cutoff performance across a broad wavelength range, and superior stability under varying humidity and temperature conditions.
Linear generator
A linear generator is used to create a uniform straight line as a reference, commonly applied in alignment tasks, as well as in machinery, construction, and manufacturing industries. In addition, this type of lens can also be utilized in low-power lasers. We offer customers lenses with full angles of 7°, 10°, 30°, 45°, 60°, 75°, and 90°, tailored to meet a wide range of application needs.
