12.5mm Dia x 10mm FL, NIR I Coated, Molded Aspheric Condenser Lens

Product Details High Numerical Apertures Fully Documented for OEM Integration Ideal for Illumination Applications TECHSPEC Molded Aspheric Condenser Lenses have been designed for integration into the illumination path of OEM instrumentation. Available in 5 to 50mm diameters, the small diameter lenses are ideal for medical devices or portable instruments, while the larger lenses are typically integrated into benchtop analytical equipment including biotech instruments such as DNA sequencers and polymerase chain reaction (PCR) testing platforms. The front aspheric surface is molded to eliminate spherical aberrations, while the second surface is ground and polished for improved performance. Full prescription data and drawings are available to aid in design integration. Note: For custom coating options, please contact us .
