TECHSPEC® NIR I Coated Plano-Concave (PCV) Lenses are designed to bend parallel input rays to diverge from one another on the output side of the lens causing this lens to have a negative focal length. These lenses can be used for balancing aberrations created by other lenses within a system due to their negative spherical aberration. Plano-Concave (PCV) lenses are commonly used in a variety of applications including image reduction, beam expansion and telescopes. TECHSPEC® NIR I Coated Plano-Concave (PCV) Lenses offer optimal performance in the 600nm to 1050nm range. These lenses are also available Uncoated, VIS-EXT, MgF2, VIS 0°, VIS-NIR, YAG-BBAR, or with NIR II AR coating options.

Typical transmission of a 3mm thick, uncoated N-BK7 window across the UV - NIR spectra. |
 |
Typical transmission of a 3mm thick N-BK7 window with MgF2 (400-700nm) coating at 0° AOI. The blue shaded region indicates the coating design wavelengh range, with the following specification: Ravg ≤ 1.75% @ 400 - 700nm (N-BK7) Data outside this range is not guaranteed and is for reference only. |
 |
Typical transmission of a 3mm thick N-BK7 window with VIS-EXT (350-700nm) coating at 0° AOI. The blue shaded region indicates the coating design wavelengh range, with the following specification: Ravg ≤ 0.5% @ 350 - 700nm Data outside this range is not guaranteed and is for reference only. |
 |
Typical transmission of a 3mm thick N-BK7 window with VIS-NIR (400-1000nm) coating at 0° AOI. The blue shaded region indicates the coating design wavelengh range, with the following specification: Rabs ≤ 0.25% @ 880nm Data outside this range is not guaranteed and is for reference only. |
 |
Typical transmission of a 3mm thick N-BK7 window with VIS 0° (425-675nm) coating at 0° AOI. The blue shaded region indicates the coating design wavelengh range, with the following specification: Ravg ≤ 0.4% @ 425 - 675nm Data outside this range is not guaranteed and is for reference only. |
 |
Typical transmission of a 3mm thick N-BK7 window with YAG-BBAR (500-1100nm) coating at 0° AOI. The blue shaded region indicates the coating design wavelengh range, with the following specification: Rabs ≤ 0.25% @ 532nm Data outside this range is not guaranteed and is for reference only. |
 |
Typical transmission of a 3mm thick N-BK7 window with NIR I (600 - 1050nm) coating at 0° AOI. The blue shaded region indicates the coating design wavelengh range, with the following specification: Ravg ≤ 0.5% @ 600 - 1050nm Data outside this range is not guaranteed and is for reference only. |
 |
Typical transmission of a 3mm thick N-BK7 window with NIR II (750 - 1550nm) coating at 0° AOI. The blue shaded region indicates the coating design wavelengh range, with the following specification: Rabs ≤ 1.5% @ 750 - 800nm Data outside this range is not guaranteed and is for reference only. |
