China Variable Attenuation Filter Camera Lens Optics

250-2500nm Transmission Adjustable Variable Attenuation Optical AttenuatoDrying Machine rVariable Attenuation Filteris areflective attenuation filter that can change the light transmittance by linear movement or rotation. By rotating or moving, the luminous flux can be continuously adjusted to obtain arbitrary brightness, and the relative change in transmittance can more easily adjust the luminous flux dynamically. It can be Package & Printing Service gradually attenuated in the range of OD1-OD4 according to customer requirements.
