CaF2 (Calcium Fluoride) Double Concave Lenses are high-precision optical components manufactured from high-purity calcium fluoride single crystals. Featuring two concave surfaces, these negative focal length lenses are designed for beam expansion, image projection, and optical system miniaturization, offering exceptionally high transmission from the ultraviolet (UV) through the visible and into the infrared (IR) spectrum with minimal chromatic aberration.

CaF2 (Calcium Fluoride) plano-concave lenses are high-performance negative optical elements manufactured from high-purity calcium fluoride single crystals. Featuring one flat surface and one concave surface, these lenses provide a negative focal length used for beam divergence, projection systems, and optical path expansion, boasting exceptionally wide transmission from the ultraviolet (UV) through the visible and into the infrared (IR) spectrum with minimal wavefront distortion.

Silicon (Si) plano-concave lenses are high-performance negative optical elements manufactured from optical-grade monocrystalline silicon. Featuring one flat surface and one spherical concave surface, these lenses provide a negative focal length ideal for beam expansion, divergence control, and optical system miniaturization in the infrared spectrum, boasting high refractive index and excellent thermal conductivity.
