Stouffer Scanner Scales are available in a variety of formats for use on flat-bed or drum scanners. Guides are made in many sizes, stepped or stepless, black and white, transmission or reflection. Resolution patterns can be added to some scales. One of the most popular guides used is the R3705 37 Step Scanner Scale with density increments of .05 optical density. 

RoHS-Compatibility:
Products manufactured and sold by Stouffer Industries are RoHS compliant. All step wedges, step tablets, gray scales, and any other photosensitive quality control device made contain no or less than agreed levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants.

Longlivety:
Stouffer Step Tablets and Gray Scales are made under controlled conditions to meet or exceed the requirements for archival permanence following procedures recommended by the manufacturers of the materials. Archival permanence is usually defined up to 10 years or more. Studies at the National Institute of Science and Technology have shown that the densities of this kind of step tablet will remain stable for at least four years when handled and stored with care.

The primary causes of degradation are use, followed by ( in no particular order) heat, humidity, fingerprints, splashes including spittle, chemical fumes and vapors, attempts to clean the emulsion with anything other than a soft camelhair brush, and abuse.A quality control device that is handled 40 times a day will degrade faster than one that is handled once a week. The user should set a routine to determine the frequency of replacement based upon factors occurring in-house and the foregoing discussion.

We recommend to change the step wedge after 3-6 months and immediately at visual damage

Calibration:
This step wedge is also availabe in calibrated version. Lead time about 4 weeks
