Product Overview

45° Beam Angle in a Compact PC Lens

The L528 is an extruded polycarbonate optical lens featuring a nominal 45° beam angle and a cross-section measuring 19.8 mm wide × 9.5 mm high. It offers an optical option for linear luminaires intended for architectural accents, retail displays and other targeted lighting applications. Select the L528 by matching its mounting geometry to your profile and evaluating its light distribution with the intended LED board. Both mechanical fit and optical performance should be assessed within the complete fixture design.

Nominal 45° Beam Angle — A defined optical specification for evaluating targeted linear lighting.
19.8 mm Lens Width — A compact cross-section for compatible profile assemblies.
9.5 mm Lens Height — A key dimension for checking internal space and LED clearance.
PC Construction — A polycarbonate optical component for LED linear luminaires.

Dimensions & Mounting

Check the 19.8 × 9.5 mm Cross-Section

The L528 measures 19.8 mm in overall width and 9.5 mm in overall height. Use the detailed lens drawing to compare the seating surfaces, retaining features and clearances with your aluminum profile. When assessing profiles described as approximately 20 mm wide, check the actual lens opening and mounting interface. A similar nominal width does not confirm compatibility.

Mounting Interface — Compare the lens seating and retaining geometry with the profile drawing.
Assembly Clearance — Check the space required for the lens, LED board and mounting components.
LED Position — Confirm emitter alignment and the intended lens-to-LED distance.

Optical Performance

Evaluate the 45° Beam in Your Assembly

The L528 has a nominal 45° beam angle. Actual light distribution depends on the LED source, emitter arrangement and position relative to the lens. Evaluate the assembled luminaire at the intended working distance and orientation. Review coverage and uniformity on the relevant target surfaces using optical data or measurements for that configuration.

Nominal Beam Angle: 45°
Evaluation Inputs: LED model, emitter spacing and lens-to-LED position
Installation Factors: Working distance, target surface and desired coverage

Product FAQ

Before you choose L528 45° Extruded PC Optical Lens for LED Linear Lighting — 19.8 × 9.5 mm

What are the dimensions of the L528 lens?

The L528 measures 19.8 mm wide × 9.5 mm high, approximately 0.78 × 0.37 inches. These are the overall cross-section dimensions.

What material is the L528 made from?

The L528 is made from polycarbonate (PC). Include any specific material-grade or documentation requirements in your inquiry.

What is the beam angle of the L528?

The nominal beam angle is 45°. Evaluate the resulting distribution with the intended LED source and assembly geometry.

Will the L528 fit a 20 mm LED profile?

Compatibility cannot be confirmed from the nominal profile width alone. Compare the actual opening, retaining features, lens seating position and internal clearance with the L528 cross-section.

What information is needed for an L528 quote?

Include the required lens length and quantity, profile drawing, LED board details and intended application. Add your sample requirements and target delivery date where available.
