This varifocal aspheric lens combines the advantages of larger format sensors with the flexibility of an adjustable focal length. It's great for high-end imaging when a manually adjustable focal length is needed.
Transmission extends in to the NIR range, with 50% transmission at 860 nm. (See the Resources tab for the curve.)
This lens, with a metal body, has locking screws to keep the iris and focus in position. When combined with a 1" (16 mm) sensor, it offers a zoom ratio of 4x.
