FAQ
A: They are widely used for microscope objective modules, CMOS/CCD image sensors, machine vision cameras, optical detection equipment, fluorescence microscopy and biotech testing. The black ink ring effectively blocks stray light, eliminates background interference and improves imaging contrast.
A: Yes. We support custom outer diameter, clear aperture size, glass thickness (0.17mm, 0.3mm, 0.5mm, 0.7mm, 1.0mm etc.). Optional coatings include AR anti-reflection coating, IR block coating, anti-fingerprint coating and customized black shading ink.
A: Microscope objectives are optically calibrated for specific glass thickness. Excessive thickness deviation will introduce spherical aberration, resulting in blurry images. We can control tight thickness tolerance ±0.02mm for precision optical applications.
A: Standard material is aluminosilicate. We also provide soda lime glass, quartz glass (for UV transmission) and D263T thin glass upon request to satisfy different wavelength transmission requirements.
A: Handle edges only to prevent fingerprint contamination. Clean with lint-free optical cloth mixed with ethanol. Store in original release film packaging under dry, dust-free environment. Avoid scratching the optical clear area and peeling the black printed ring.
