BAC151B ‒ Raman Video Microsampling System

B&W Tek, Inc.

The BAC151B Raman video microscope sampling system allows you to convert any of B&W Tek's Raman systems into a Raman microscope It is compatible with our laboratory Raman probes and is designed to provide you with the highest level of flexibility and sampling utility. The BAC151B’s optional dual laser wavelength configuration allows you to use one port with two different input laser wavelengths. If you already have both a 532nm and a 785nm Raman system, you only need one BAC151B to use with both systems. We also offer individual 532nm, 785nm, and 1064nm versions.The integrated camera facilitates precision Raman sampling through BWSpec™, which allows for laser beam tracking and image capturing. With tripod accessories available, the microscope head can be mounted to the tripod easily as well.BAC151B ‒ Raman Video Microsampling System Features: Tripod Mounting Accessories with 1D, 2D, and 3D Adjustment Compatible with All B&W Tek Raman Systems Accepts Standard Microscope Objectives Video Camera for Sampling Viewing Coarse and Fine XYZ Adjustments Dual Laser Wavelength Port
