The Plano-Concave Lens have one flat surface and one concave surface. They have a negative focal length and are used to diverge incoming light, or to increase focal length in an existing optical system. They can be used in beam expanders and projection systems.
 
CLZ Precision Optics specialize in manufacturing optical components from customer supplied designs, including a wide variety of Plano Concave Lenses. We can provide Featuring surface accuracy to less than 0.2 fringe measured at **3nm and finishes to ****0 scratch-dig per MIL-PRF ****0, the material are fabricated from quartz, optical glass, silicon, etc. and the sizes up to **0mm diameter.
