TECHSPEC Uncoated Plano-Concave (PCV) Lenses
From fast modifications to stock optics to custom designs, we can help you take your optical system from design to prototype to volume production. Contact us to get started today.
TECHSPEC® Uncoated 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® Uncoated Plano-Concave (PCV) Lenses offer optimal performance in the 350nm to 2200nm range. These lenses are also available VIS-EXT, MgF2, VIS 0°, VIS-NIR, YAG-BBAR, NIR I, or with NIR II AR coating options.

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. |
