Wholesale Optical LED Laser BK7 Biconcave Custom Double Concave
Lens The Wholesale Optical LED Laser BK7 Biconcave Custom Double Concave
Lens is a precision-engineered optical component specifically designed
for advanced laser and LED applications. Manufactured from
high-quality BK7 optical glass, this lens provides excellent
transmission in the visible and near-infrared spectrum (350-2,000
nm) while maintaining low internal stress and minimal optical
aberrations. The biconcave (double concave) geometry diverges light
beams effectively, making it ideal for controlling laser beam
diameter, expanding LED illumination, or collimating light in
compact optical assemblies. With customizable diameters, focal lengths, and surface quality
standards (commonly 40/20 or 20/10 scratch-dig), the Wholesale Optical LED Laser BK7 Biconcave Custom Double Concave
Lens ensures consistent optical performance in both laboratory and
industrial environments. Anti-reflective coatings can be applied to
improve transmission efficiency, reduce surface reflections, and
enhance system reliability. This lens is widely adopted in
applications requiring precise beam shaping, high uniformity, and
reliable long-term optical stability. Specification
