basic information
■Features and Strengths - Precise adjustment of light quantity Used to attenuate incoming light and adjust light levels. Made from 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 quantity with a constant attenuation level. - Step Filter Coated with a gradually changing film thickness within the plane. Gradually controls light quantity. - Slide Filter Coated with a linearly and continuously changing film thickness. Allows continuous control of light quantity by sliding. - Circular / Wedge Filter Coated with a continuously changing thickness in the circumferential direction of a circular substrate. Allows continuous control of light quantity by rotation. - Gradient Filter Coated to change transmittance from the center of the substrate to the periphery. A filter that equalizes light quantity. Compatible with various substrate shapes. For detailed specifications, please download the product catalog.
