N-BK7 Mounted Plano-Concave lenses, Uncoated
Our LINOS® Singlets are available in a wide range of focal lengths and diameters, allowing you to select the ideal components for your application. We use only premium materials from trusted manufacturers and maintain strict tolerances to ensure exceptional quality. Each lens is offered in both a mounted version with a high-quality, black-anodized, engraved aluminum mount and an unmounted version for flexible integration.
Our mounted plano-concave lenses integrate seamlessly with LINOS Microbench and Nanobench systems. Tight focal-length tolerances ensure consistent integration and reliable optical performance. The plano-concave lenses deliver precise optical performance for applications requiring controlled beam divergence. The uncoated N-BK7 singlets are well-suited for a broad wavelength range.
ZEMAX files are available to simplify optical design and simulation. For custom specifications or large production volumes, contact us today to discuss your requirements or to request more information.
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%
Note: Dmech: outer mount, DCA: clear aperture, Doptical: optical size, RR: retaining ring
