basic information
■Features and Strengths - Precise adjustment of light intensity Used to attenuate incoming light and adjust light levels. It employs thermally stable materials with minimal changes in optical properties due to variations in incident angle and polarization. - Designed according to the wavelength, incident angle, and polarization state of the light used - Customizable shape, size, and attenuation level ■Functions and Mechanism - ND Filter Controls light intensity with a constant attenuation level. - Step Filter Coating with a gradually changing film thickness within the plane. Gradually controls light intensity. - Slide Filter Coating with a linear, continuous change in film thickness. Allows continuous control of light intensity by sliding. - Circular / Wedge Filter Coating that continuously changes in the circumferential direction of a circular substrate. Allows continuous control of light intensity by rotation. - Gradient Filter Coating that varies transmittance from the center of the substrate to the periphery. A filter that equalizes light intensity. Compatible with various substrate shapes. For detailed specifications, please download the product catalog.
