High Precision Aspheric Lens | Custom K9/BK7 Optic for Medical & Industrial Equipment

 

With 20+ years vertical optical glass industrial chain, we are trusted supplier of precision optical component for 180+ medical brands, industrial automation factories and university labs across USA, EU, Australia. Our core product High Precision Aspheric Lens solves the biggest pain of traditional optical assemblies.

 

Core Pain Point We Solve

 

Common spherical lens causes severe spherical aberration, low light transmittance and fuzzy imaging, leading to unstable equipment operation & high after-sales maintenance cost. Our exclusive polished low distortion aspheric lens corrects aberration thoroughly, paired with customized AR coating to reach 99.5% visible light transmittance, cutting your optical system failure rate by 73%. As professional medical industrial optical lens, our tailor-made custom K9/BK7 glass lens becomes your top pick for high-precision equipment, a typical premium high transmittance lens.
