473nm optical filter

Precision optical filter family centered at 473 nm (deep blue / DPSS laser line), available in three configurations: narrow bandpass filter (transmit 473 nm, block others), notch dichroic mirror (reflect 473 nm, transmit others), and cold mirror (short wave pass — reflect visible, transmit IR).

Fabricated on UV-grade fused silica or N-BK7 substrate with hard dielectric multilayer coating via ion-assisted deposition. Ideal for 473 nm DPSS laser purification, fluorescence microscopy (GFP / FITC alternative), Raman spectroscopy, flow cytometry, and laser-based display systems.

Fully customizable in diameter, thickness, and mounting configuration.
