Unmounted N-BK7 Plano-Concave Lenses, ARB2-VIS
Our LINOS® Plano-concave lenses are offered in a wide range of focal lengths and diameters, allowing you to meet the specific needs of your application. They are made from premium materials from trusted manufacturers and maintain strict tolerances to ensure exceptional quality. The ARB2 VIS broadband anti-reflection coating ensures high transmission across the 450–700 nm wavelength range while offering excellent resistance to laser-induced damage. Each lens type is offered both unmounted and with a high-quality, black anodized engraved aluminum mount.
Our plano-concave lenses are supplied unmounted for flexible integration into your optical system. Their narrow focal-length tolerances ensure consistent performance and reliable optical behavior. These lenses deliver precise results in applications requiring controlled beam divergence. Each standard lens features double-sided anti-reflection coatings optimized for the visible (VIS) wavelength range for higher transmittance.
ZEMAX files are supplied to assist with optical design and simulation. For customized requirements or higher-volume manufacturing, contact us to provide a quote tailored to your technical specifications.
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' = sagittal height secondary vertex, F, F' = focal points, H, H' = principal points; Tolerances: focal length f: ±2% image distance s': ±2%
Specifications broadband anti-reflective coating ARB2 VIS:
- Guaranteed residual reflection < 0.5 % for angles of incidence 0° ≤ AOI ≤ 15° in the AR range
- Typical average residual reflection < 0.3 % for angles of incidence 0° ≤ AOI ≤ 15° in the AR range
- Damage threshold H∞ > 30 J / cm² for 11 ns laser pulses (s‑on‑1) at 1064 nm and 10 Hz
- AR range typical: 450–700 nm
- Design adaptable to the spectral range of 350 nm ≤ λ ≤ 950 nm and to higher angles of incidence
