Compact Automated Multiphoton Microscope
CAMM is an inverted multiphoton laser scanning system best suited for histological samples for coregistration of large field-of-view forward detected second harmonic generation photons and brightfield built on an ASI RAMM frame that uses a tunable Coherent MIRA900 laser excitation source (S/N 96994) for imaging from 700-1000 nm pumped by a Coherent VerdiV10 (S/N V10-G9920) with XY scanning control by Cambridge 6210 galvos. CAMM excitation is modulated by a Conoptics 350-80-LA Pockels cell (S/N 353273BK) with a Hamamatsu H7422-40P detector to collect forward scattered SHG photons via the 780 nm tuned excitation source used in conjunction with a ThorLabs MF390-18 excitation filter. CAMM's brightfield scanning system is equipped with a 01-QIClick-F-CLR-12 Color 12 BIT CCD Camera (S/N Q29664) to screen histological samples for tumor associated collagen signatures (TACS) and an ASI Continuous Reflection Interface Sampling and Positioning (CRISP) system (S/N 8) for continuous focus stability and reduced hourly drift <0.1μm for longer scans. The extended field-of-view multiphoton and white light images automatically stitch and register using the open source image analysis software FIJI/ImageJ for automated TACS scoring on the sample using the open source CurveAlign software tool developed by LOCI lead scientist Yuming Liu.
Class IV Laser: Safety goggles for CAMM are located in room 159B on the hook on the wall offering protection for 740-1100 nm light. CAMM uses a Class IV Coherent Mira 900 (#SN 96994) Ti:Sapph pulsed laser and a Class IV Coherent Verdi-V10 (#SN V10-G9920) diode-pumped solid-state CW laser. Engineers may wish to refer to the American National Standard for Safe Use of Lasers and follow LOCI's General Laser Safety Guidelines.
