FLT Lens Series

for Seoul

LEDs

 High efficiency

 Available in 3 different beams

 Easy assembly

The FLT lens series offers three lenses

specifically designed for compatibility with Seoul

LEDs.

A software-optimized aspheric profile combined

with shaped front surfaces and micro-lenses

provide several different beam output patterns:

medium, wide and elliptical beams

The design of the FLT series insures that almost

all of the light emitted by the LED is captured and

usefully directed, resulting in a lens with maximum

performance and efficiency.

The FLT series is available as lenses alone or as

assemblies in black, white or transparent holders.

The lens assemblies allow for easy and accurate

assembly of the FLT lens to your LED and fixture.

Typical applications are:

 Reading lamps

 MR11 and MR16 Fixtures

 Signs

 Architectural Lighting

General Characteristics

Materials

Lens Material Optical Grade PMMA

Holder Material Polycarbonate: Transparent, White or Black

Operating Temperature range -40° C / + 80° C

Storage Temperature range -40° C / + 80°C

Average transmittance in visible spectrum (400 – 700nm) >90%, as measured using 3mm thick

Optical Grade PMMA.

Please note that flow lines and weld lines on the external surfaces of the lenses are acceptable

if the optical performance of the tri-lens is within the specification described in the section

“OPTICAL CHARACTERISTICS”

IMPORTANT NOTE – Lens handling and cleaning:

 Handling: Always use gloves to handle lenses and/or handle the lenses only by the

flange. Never touch the outside surfaces of the lenses with fingers; finger oils and

contamination will absorb or refract light.

 Cleaning: Clean lenses only if necessary. Use only soap and water to clean the

surfaces and lenses. Never expose the lenses to solvents such as alcohol, as it will

damage the plastic.
