40.5mm 665nm Pro Slim Infrared Lens Filter – 20% Off Clearance Item
Clearance filters will arrive with cosmetic defects. Examples of a cosmetic defect are light surface scratches, smudged AR coating, or other small defects in the filter glass itself. This issues will have very little to no effect whatsoever on image quality. However, due to their appearance, they can not be sold as brand new, unused items.
These external infrared filters are perfect for adding to a full spectrum conversion or on top of another infrared conversion to get a different effect. These are high quality polished optical glass IR filters, each with standard front and back threads.
These professional grade filters are our finest filters. All of our pro filters are AR coated and come in our new slim filter ring.
- Anti-reflective (AR) coated to increase light-transmission and reduce flare and ghosting
- Slim filter ring for reduced vignetting when using wide angle lenses or when stacking filters
- Front and rear threaded unlike other slim filters
- 6061 aircraft aluminum construction for a light and strong ring
- Teflon coated threading for easier installation and reduced seizing
- Finger grips for easier filter removal
