MiniRam spectrometer systems feature patented CleanLaze™ technology with linewidth as narrow as 0.03nm when equipped with a 785nm laser. This technology ensures the correct centre wavelength and avoids the phenomenon of “mode hopping.” In addition, the laser output power can be adjusted in the software from 0 - 100%, allowing you to maximise signal to-noise ratio and minimise integration time.

MiniRam is configurable for either 785nm or 532nm laser excitation wavelengths. With our Crossed Czerny-Turner optical design, spectral resolution of 10cm-1 is achieved, whilst simultaneously providing a small footprint which is an enormous advantage for field based Raman applications.

MiniRam spectrometers feature thermoelectrically cooled array detectors, which is a highly effective way to reduce dark current and noise to enhance the dynamic range and detection limit.

The graphs (left) show dark current and noise for an uncooled versus a cooled CCD detector at an integration time of 30 seconds. Operating at room temperature, the dark current nearly saturates the uncooled CCD. When the CCD is cooled to 14°C, the dark current is reduced by 4x. This allows the spectrometer to operate at long integration times and detect weak optical signals.

i-Raman™ is unique for its high resolution and portability. With performance comparable to large bench-top Raman systems and weighing less than 10 lbs, it’s a portable laboratory instrument available at a fraction of the cost of many other large footprint Raman instruments.

The i-Raman spectrometer is configurable for either 785nm or 532nm laser excitation wavelengths. Our double pass transmission optics provide research grade spectral resolution of 3cm-1, and the high throughput f/2 optical design gives more efficient collection of the Raman signal. We have two versions – one with a wider than normal spectral range, whilst still providing exceptional resolution.

The detector is TE cooled to -20ºC for minimum dark current and maximum dynamic range. A back-thinned CCD provides 90% quantum efficiency, which is a vast improvement over conventional front illuminated devices (compare the two curves in the figure opposite – the front illuminated response is the lower black curve).

B&W Tek’s proprietary GemID software, powered by GemExpert has a user friendly GUI which allows you to easily choose to verify a known gemstone or identify an unknown sample by measuring the spectrum and then comparing it to that of the GemExpert library.

The GemExpert Library, developed by Professor H.A. Hanni and Professor Johannes Hunziker, contains spectra for almost 400 different gemstones. Each entry of the library contains the commercial name, an image, the country of origin and other useful information to help verify/identify samples quickly and easily.
