355230-B 6.325 mm Dia. D-ZLAF52LA Molded Glass Aspheric Lenses; EFL=4.5 mm; NA=0.55 AR 600-1050nm

The 355230-B is a high-quality aspheric lens, precision-molded from D-ZLAF52LA glass, a unique material with exceptional optical properties. This lens boasts a diameter of 6.325 mm and a center thickness of 2.708 mm, making it suitable for a wide range of applications. The lens features an effective focal length (EFL) of 4.5 mm, which is a crucial parameter for determining the lens's magnification power.

The lens's design includes a front radius (R1) of 0 mm and a back radius (R2) of -3.576018 mm, which contributes to its high optical performance. The lens's numerical aperture (NA) is 0.55, indicating a wide acceptance angle and high light-gathering capability. This makes the lens ideal for use in systems requiring high resolution and high light throughput.

The 355230-B lens comes with broadband anti-reflection coatings on both the front and back surfaces, optimized for the 600-1050 nm wavelength range. This coating significantly reduces surface reflections, improving the overall transmission of the lens and reducing unwanted ghosting and flaring effects.

This lens is sourced from Thorlabs, a leading manufacturer of optical components, ensuring a high level of quality and reliability. The lens is currently in stock, according to the vendor's website, making it readily available for immediate use.
