Glass small aperture
Overview
GA Series glass apertures/slits: borosilicate glass (optional Thermanox #1 coverslip), ø25mm standard disc, transparent and non-conductive, for phase sifting, microscopy, MEMS and anodic bonding, hole sizes 5-500µm.Description
【Product Overview】
The GA Series glass apertures and slits are precision-made from borosilicate glass (optional Thermanox #1 coverslip) in a ø25mm standard disc. The glass material offers transparency, non-conductance and non-isolation, making it ideal for applications where metal apertures cannot be used, across telecom, medical, pharmaceutical and optical industries.
【Key Features】
(1) Borosilicate glass / Thermanox, transparent, non-conductive, non-isolating;
(2) ø25mm standard disc, thickness 0.16-0.25mm;
(3) Circularity > 5µm, centering ±0.25mm;
(4) Hole sizes 5-500µm, custom arrays available;
(5) MOQ 5 pcs per size.
【Typical Applications】
Phase sifting, microscopy, MEMS and anodic bonding, telecom/medical/pharmaceutical/optical industries, optical paths requiring transparent or non-conductive media.
