Cylindrical Plano-concave Lens (BK7) / CLB-3030-150NIR1
Contact us
◦BK7 lenses are also available with three types of anti-reflection coatings, visible wavelength range, in the near-infrared range and in the infrared range.
◦Cylindrical lenses are often used in an optical system to change the shape and aspect ratio of the illumination light beam.

Guide | ▶Lenses are available in a large selection and in custom sizes and focal lengths. ▶In addition to our standard coating we offer custom anti-reflective coating at specific wavelengths. ▶We offer holders to mount our catalog cylindrical lenses |
Attention | ▶The cylindrical plano-concave lens has chromatic aberration, and the focal length will vary depending on the wavelength. Please check the wavelength characteristic of the focal length data for the focal lengths of each wavelength. |
