This single element lens gives an increase in output compared with the 3-element lenses with a small reduction in beam quality.
- Lens Material: Single element; Coated optical glass
- Lens Holder: 9mm x 0.5mm thread, 9mm length, blackened brass
- EFL (Effective Focal Length): 8.0mm
- CA (Central Aperture): 3.7mm
- SD (Diode to lens): 5.86mm
- NA (Numerial Aperture): 0.28mm
- Coating:400-700nm
This lens is an intermediate option between the 3-element lenses that give the best beam quality but lower efficiency and the OFL3 (G2 type) lens with the highest efficiency but a very short working distance and reduced beam quality.
