Phase One Achromatic + Digital Back
Overview:
The Achromatic + Digital back is basically a Phase One P45+ with all "Bayer" CCD colour filtration removed. Thats not all though. The Achromatic Plus is subjected to the highest levels of quality controls. Special attention is paid to calibration and spectral sensitivity as well as ensuring a "flawless" image.
It is designed to integrate with all major conventional Medium Format, Large Format and Technical Cameras in addition to customized 'camera’ solutions and Photogrammetry system.
Black and White Photography, Select Spectrum Imagery and False Color Infrared and/or Ultraviolet Imaging has a newly defined horizon without the limitaions common in ordinary colour imaging systems.

B+W UV Black Filter 403 [UG ¡]
Not to be confused with UV-blocking filters that photographers normally refer to as “UV Filters”, this one passes UV A radiation (320 to 385 nm), but blocks visible light and looks pitch-black to our eyes. It is used with appropriately sensitized films in such applications as ultraviolet reflection photography in forensics or in materials research, but also as filters on UV-emitters for fluorescence photography. Depending on the illumination and on the film’s sensitization, its filter factor is in the range of 8 to 20.

B+W Infrared Filter 092 (˜ 89 B) [RG 695]
The nearly opaque B+W Infrared Filter 092, which looks dark purplish red when held in front of a light source, blocks visible light up to 650 nm, and passes only 50% of the radiation just below 700 nm (thus the dark red color). From 730 nm to 2000 nm, transmission is greater than 90%. This makes photographs of pure red and infrared images possible with the best utilization of the relatively low sensitivity of infrared films. As the sensitization of infrared black-and-white films barely extends beyond 1000 nm, the red portion that is transmitted still makes a relevant contribution to the exposure. That is why this filter is the preferred filter for pictorial photography on IR black-and-white film. Its filter factor is 20 to 40.

B+W Infrared Filter 093 (˜ 87 C) [RG 830]
This B+W Infrared Filter blocks the entire visible spectrum, so to our eyes it looks completely opaque. Unlike the infrared filter described above, it makes pure infrared photographs possible without the visible red component. Its transmission only begins to exceed ¡% at 800 nm, rising to 88% at 900 nm, and remains that high far beyond the upper limit of sensitization covered by infrared films. This filter is used less frequently in pictorial photography because of the dramatic loss of effective ISO. But in the scientific field, materials research and forensics, the limitation to a strictly infrared range is often important. The filter factor is very dependent on the illumination and on the characteristics of the film.
