Khatod Optoelectronic Optics - Lenses PLL2056SR77

The product is a silicone lens designed for LED applications, specifically identified as part number 1621-1201-ND. It features a full angle of approximately 60¬8 at 50% intensity and around 130¬8 at 10% intensity, making it suitable for focused lighting applications. The lens is compatible with various LED types, particularly those with a 13mm light-emitting surface (LES), and has been tested for thermal shock resistance up to 120¬8C without physical deterioration. The lens assembly requires M3/M4 screws and should be press-fitted, with a maximum recommended tightening torque of 0.5 to 0.6 Nm. Additionally, it has passed water penetration resistance tests, indicating its suitability for environments where moisture exposure may occur. The lens is designed to maintain optical performance despite acceptable flow lines and weld lines on its surface. Engineers considering this lens should note its operational temperature range of -40¬8C to 150¬8C for the silicone material and -40¬8C to 120¬8C for the polycarbonate holder. The product is intended for use in the manufacture of various lighting products, and any modifications or misuse may void the warranty.
