The housing offers live LCD readout of the filter's wavelength output (accurate to 0.1Å) and red /blue wing shift buttons that can precisely tune wavelength up or down for Doppler studies. The unit operates at 12VDC for field or battery use, included is a 100-240 power supply with US, European, UK and Australian adapter wall plates and even includes a serial port for computer control capability for on-screen display of filter readout. The new Quantum Series body style is all about ease of operation.... total simplicity.

Our Quantum PE grade series is designed for professional research studies and applications in which precision homogeneity and onband transmitance values across the substrate surface are required. These filters require additional quality control steps and additional fabrication and testing time.
