Custom Optical Red Glass Discs HB3 HB6

  Custom Optical Red Glass Discs HB1 HB3 HB5 HB6   Introduction to HB-Series Red Absorptive Glass Filters The HB series (HB1, HB3, HB5, HB6) comprises red-colored glass filters that operate on the principle of absorption. These filters are manufactured by melting raw materials with specific metal oxides and dopants, which give the glass its characteristic property of absorbing shorter wavelengths and transmitting longer wavelengths.   They are part of a classic classification system for colored optical glass. Their key function is to effectively block ultraviolet, violet, blue, and green light, while transmitting red and near-infrared (IR) light. The different codes (HB1, HB3, etc.) denote specific chemical compositions that result in distinct spectral transmission profiles.   Specification: Key Characteristics:   · Type: Absorption Filter · Color: Red (varying shades) · Material: Optical Glass · Primary Function: To transmit long wavelengths (red, near-infrared) while completel…
