It features two concave surfaces with equal curvatures, designed to increase the divergence of a light beam. This lens is commonly used in optical systems to alter the focusing characteristics of light, particularly for applications such as expanding the focal length of optical systems, beam expansion, image reduction, and projection. Due to its negative focal length, the fused silica double-concave lens effectively diverges parallel incident light.<\/p>\n<p><strong>Key Features<\/strong><\/p>\n<ul>\n<li><strong>High Optical Transmission<\/strong>: Offers excellent light transmission, making it ideal for high-precision optical systems.<\/li>\n<li><strong>Thermal Stability<\/strong>: Maintains excellent optical performance even under high-temperature conditions, ensuring stable operation.<\/li>\n<li><strong>Chemical Stability<\/strong>: Provides strong resistance to chemical corrosion, making it suitable for use in harsh environments.<\/li>\n<li><strong>Precision Manufacturing<\/strong>: Features precision cutting and polishing processes, ensuring smooth surfaces and optical accuracy.<\/li>\n<li><strong>Coating Options<\/strong>: Available with anti-reflection coatings to reduce surface reflections and improve optical efficiency.<\/li>\n<\/ul>\n<p><strong>Applications<\/strong><\/p>\n<ul>\n<li><strong>Beam Expansion and Projection<\/strong>: Widely used in laser systems, projectors, and other optical devices to expand beam divergence.<\/li>\n<li><strong>High-Precision Optical Systems<\/strong>: Due to its stability and accuracy, it is commonly used in sensitive optical instruments and sensors.<\/li>\n<li><strong>High-Temperature Environments<\/strong>: Suitable for high-power laser and high-temperature applications, maintaining stable optical performance.<\/li>\n<li><strong>Focal Length Adjustment in Optical Systems<\/strong>: Plays a crucial role in increasing the focal length of optical systems, contributing to optical system design.<\/li>\n<li><strong>Scientific Research and Industrial Applications<\/strong>: Provides exceptional solutions for high-performance applications in optical research, laser physics, and imaging systems.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"[tp_attributes num_attributes=\"5\"]\n<div tabindex=\"0\" role=\"article\" data-tabster=\"{&quot;groupper&quot;:{&quot;tabbability&quot;:2},&quot;focusable&quot;:{}}\" data-content=\"ai-message\" aria-labelledby=\"qCjP5C64NhAdgRPyfetDd-author} qCjP5C64NhAdgRPyfetDd-content-0\">\n<div id=\"qCjP5C64NhAdgRPyfetDd-content-0\">\n<p>Fused silica double-concave lens is a precision optical component designed for controlled beam expansion, minimized spherical aberration, and superior ultraviolet and infrared transmission.
