Monochromators

Optometrics Corporation has, for more than thirty years, designed and manufactured optical components and instruments for university, industrial and government laboratories and the OEM markets.

Optometrics Corp. has manufactured over 20,000 Mini-Chrom monochromators since their initial introduction in 1978. The majority have been incorporated into a variety of analytical and biomedical instruments made and marketed by leaders in their respective fields. 

For those customers wishing to configure their own optical systems built around or to equip their laboratory with modules that work with the popular Mini-Chrom monochromator, Optometrics has designed compatible systems. These include a light source, sample chambers, stepping motor controller and detector. Customers can also choose selected modules to configure their own variable wavelength fiber optic modules or choose the turnkey Tunable Light Sources, all built around our line of Mini-Chrom monochromators.

Standard Mini-Chrom

The Standard Mini-Chrom (MC) is a manual unit which utilizes a micrometer for wavelength selection and readout. Turning the micrometer head causes, via a precision sine bar drive, rotation of the diffraction grating which positions the desired wavelength at the exit slit.

 

Wavelength in nanometers (nm) is read directly from the micrometer head in models 01, 02, 03 and 04. Near infra-red models (05 and 06) require the micrometer reading to be doubled, to 2 nm per division, for wavelength selection and readout.

Standard Mini-Chroms are used in a variety of applications that require an inexpensive, small, yet high-performance monochromator. They are used in physics, chemistry, engineering and the life sciences for research, development and teaching. Overall dimensions in mm: 150 x 59 x 49; Weight 0.5 Kg (1.1 lbs).

The addition of a reticle and comparator converts the Standard visible Mini-Chrom (model 03) to a hand-held spectrograph. The unit (cat. no. 6-0109) can be used to identify the emission lines of various elements such as Hg and Na from a fluorescence or discharge lamp. Removal of the comparator and reticle converts the hand held spectrograph back to a standard Mini-Chrom.

Digital Mini-Chrom

The Digital Mini-Chrom (DMC) is a manually operated monochromator that utilizes a digital counter for wavelength selection. Rotation of the dial causes, via a precision lead screw/sine bar mechanism, rotation of the diffraction grating which positions the selected wavelength at the exit slit. Wavelength is read directly in nanometers (nm) from a counter on models 01, 02, 03, 04 and 05. Near infrared model (06) requires the counter reading to be doubled, to 2 nm per division, for wavelength selection and readout. Overall dimensions in mm: 139 x 59 x 49; Weight: 0.7 Kg (1.5 lbs).
 
WAVELENGTH READABILITY
The wavelength on all Digital Mini-chroms can be selected and read to 0.2nm.

Scanning Mini-Chrom

The Scanning Mini-Chrom monochromator (SMC) is designed to be driven by stepping or servocontrolled motors. No wavelength readout is provided. All models utilize a precision lead screw/sine bar mechanism to rotate the diffraction grating and sequentially position the selected wavelength(s) at the exit slit. Rotation of the drive shaft in a clockwise direction proportionately increases the wavelength of radiation at the exit slit. Scanning Mini-Chroms are used in applications requiring either single or repetitive scans of wavelength intervals or the sequential selection of discrete wavelengths. To prevent mechanical damage due to inadvertently exceeding wavelength limits, all Scanning Mini-Chroms are supplied with dual photosensors that function as high-and low-limit switches. Overall dimensions in mm: 95 x 59 x 49; Weight 0.45 Kg (1.0 lb).

Scanning Digital Mini-Chrom

The Scanning Digital Mini-Chrom (SDMC) includes an integral stepping motor which can be controlled by a calibrated drive such as the PCM-02 via a 15-pin connector. The SDMC is similar to the Digital Mini-Chrom in that it includes a four digit counter for wavelength readout and a dial for manual wavelength selection. For near-infrared model (06), the four-digit counter reading must be doubled, to 2 nm per division, for wavelength selection and readout. Dual photosensors that function as high-and low-limit switches are included for use in the scanning model. The Scanning Digital Mini-Chrom can be used for all applications that require the convenience of a built-in wavelength readout as well as applications requiring scanning to a selected wavelength or over a wavelength interval. Overall dimensions in mm: 197 x 59 x 49; Weight 0.9 Kg (1.9 lbs).
