Lycian Short Throw Lens Module
Details
The short lens system is designed for short throw applications to approximately 75' or other various uses. Using a single 6" clear optical grade lens, the short lens system can produce a beam spread from 0.62° to 11.8°. A single top mounted knob adjusts the focus in both the fixed focus application and the beam spread in variable focus applications. A friction adjustment screw, located in the lens trolley and visible when the 2020 is removed from the spotlight changes the feel of the lens knob. The type of focus is selected on the gate module.

Checkout claimed that my card was expired and would not process the order, despite card expiring April 2027. Had to use personal card instead of business card to complete the order. Additionally, items that I wanted - and were available did not appear in search.
Very efficient and great product.
Thanks
