Achromatic Lenses (Doublets) VIS 0° and VIS-NIR coated achromats are also available Correct for on-axis spherical and chromatic aberrations Custom Achromatic Lenses Available

ZnS is used widely for IR components, windows and lenses, and applied for Thermal Imaging, long-wave infrared sensors.

Fused Silica material Advantages With Good UV and IR transmission, Low thermal expansion, providing stability and resistance to thermal shock, Wider thermal operating range and High laser damage threshold make Fused Silica windows could used for Laser, Medical, imaging etc. application.

Positive meniscus lenses is convex-concave lens thicker at the center than at the edges, which frequently used for beam focusing applications. Negative meniscus lenses is convex-concave lens thinner at the center than edges, which frequently used for beam expanding applications.

Plano-Convex Lenses is best used where one conjugate point (object distance S or image distance S' ) is more than five times the other. This lens shape is near best-form for either focusing collimated light or for collimating a point source.

Made from BK7 material, which has transparent range from 330-2100nm. The refractive index is 1.5168 at 587.6nm. The BK7 window has good performance over visible and near IR spectrum for most application.
