Schott RG1000 (RG-1000) 52mm 930nm IR Infrared Longpass Filter.
*** NOTE: Experimental thickness = 1.25mm thick. ***
This filter blocks UV and visible light, and transmits infrared (IR) with 930nm @50% with this 1.25mm thickness (see graph).
This filter is quality made from genuine Schott RG1000 optically
polished filter glass. Precision crafted size, thickness, and edges. Freshly made from new glass.
Custom mounted in a quality standard sized 52mm camera filter frame (with front
and rear threads). Cut and mounted in the USA.
(Schott filter glass is the very best premium quality filter glass in the
world. If you want a quality filter then get one that is made of Schott filter
glass)
Glass: Schott RG1000 (RG-1000)
Filter thread size: 52mm
Glass thickness: 1.25mm (rare thickness, experimental)
Visual color: Opaque
Type: IR Longpass (NIR Longpass) filter (see graph above)
Used for: Infrared photography
This filter blocks light below about 750nm (visible light and all
ultraviolet), and transmits infrared light (starting at 750nm and upward, please see graph), with a 50% transmission at about 930nm with this thickness.
This filter can be used on any full spectrum converted camera for infrared
photography.
This filter could also be used on some infrared converted cameras for
adjusting a "color IR" photo to B&W IR (if the camera's internal IR filter is less than 750nm to 930nm),
and it can even be used on regular non-converted off-the-shelf stock
cameras by using longer exposures.
This filter will produce a black and white infrared image (when correctly white balanced).
I am happy to make this and other hard to find specialty filters,
sizes, thicknesses, and shapes available to you on request.
