Unmounted Fused Silica Plano-Concave Lenses, Uncoated
Our LINOS® unmounted fused silica lenses are available in a range of focal lengths and diameters, making them suitable for UV and high-power applications. We use only premium materials from trusted manufacturers and maintain strict tolerances to ensure exceptional quality. Each lens type is also available with a high-quality, black-anodized, engraved aluminum mount.
Our unmounted plano-concave lenses enable flexible, custom integration into optical systems. Their narrow focal-length tolerances ensure consistent integration and reliable optical performance, particularly for applications requiring controlled beam divergence. Manufactured from fused silica, these lenses are suitable for UV and high-power applications, offering a high damage threshold and dependable performance in demanding environments. Uncoated versions are ideal for broad wavelength use, as fused silica provides higher transmission than standard optical glass.
ZEMAX files are offered to facilitate efficient optical design and simulation. Should you require custom specifications or higher-volume production, contact us to request a quotation based on your specific requirements.
Note: f = focal length (object side), f' = focal length (image side) , s = object distance, s' = back focal length, Ø = lens diameter, dm = center thickness, dr = edge thickness, h = primary vertex (h=dm-dr-h'), F, F' = focal points, H, H' = principal points; Tolerances: focal length f: ±2% image distance s': ±2%
