Measuring Instruments

Spectrophotometer (spectral type, side port)
Featuring a d/8 optical system (diffused illumination; 8° viewing) compliant with ISO, DIN, and JIS, the CM-3700d provides a wide range of measurement functions and supports many different applications.

For precise positioning of transparent plates, films or other transparent samples for transmittance measurements. Holds the Glass Cells CM-A97 (2 mm), CM-A98 (10 mm), CM-A99 (20 mm) and the Disposal Plastic Cells CM-A CM-A130 (2 mm), CM-A131 (10 mm) and CM-A132 (20 mm) or the Flow Cell CM-A508 (10 mm) always in perfect and repeatable position for precise transmittance measurements.
The Transmission Zero Calibration Plate CM-A100 is required to block the light path for zero calibration in transmittance measurement mode. The black and mat coating of the plate absorbs also stray light within the transmission chamber of the instrument.
Glass cell made of optical glass for precise transmittance measurement of transparent liquids. The optical path is 2 mm and therefore perfect for liquids with high optical density.
Glass cell made of optical glass for precise transmittance measurement of transparent liquids. The optical path is 10 mm and recommended for liquids with normal optical density.
Glass cell made of optical glass for high precision transmittance measurement of transparent liquids. The optical path is 20 mm and recommended for liquids with normal optical density.
Disposal plastic cell with an optical path of 2 mm. Suitable for transmittance measurements of water based transparent liquids. Recommended for liquids with high density.
Disposal plastic cell with an optical path of 10 mm. Suitable for transmittance measurements of water based transparent liquids. Recommended for liquids with normal density.
Disposal plastic cell with an optical path of 20 mm. Suitable for transmittance measurements of water based transparent liquids. Recommended for liquids with lower density.
For continuous transmittance measurement of transparent liquids. The optical path of the cell is 10 mm and can be used with a pressure up to 2 Bar. The cell fits the Sample Holder CM-A96.


The PET-Pre-Form Holder CM-A504 allows a precise positioning of transparent Pre-forms in the transmission chamber of the instrument. The rail guide of the holder allows horizontal movements of the pre-form to define the area for the measurement.

High gloss black glass tile with high absorption. Due to the extreme long term stability perfect to use as background standard.

The Opacity Tool is equipped on one side with a white tile and on the opposite side with a black cavity and allows quick and precise opacity measurements of paper, films and similar materials. The Opacity Tool is set instead of the standard sample holder, but thanks to the turnable sample holder the Opacity Tool can be used also for standard reflectance measurements.
