SHALL BE IN ACCORDANCE WITH THE SALIENT CHARACTERISTICS/SPECIFICATIONS HEREIN. ITEM#1: QTY 1, CAT#8052, DESC.: LIGHT SOURCE WITH DUAL SHUTTER ASSEMBLY, FILTER CARRIER, FIBER COUPLER AND LSI Y FIBER. ITEM #2: QTY 1, CAT #8051, DESC.: VIBRATION ISOLATION SYSTEM WITH VERTICAL OPTICAL RAIL. ITEM #3 QTY 1, CAT. #8053, DESC.: VERTICAL FLUORESCENCE ILLUMINATOR WITH FIBER COUPLER. ITEM#4: QTY 1, CAT# 8056, DESC.: IMAGE SELECTOR. ITEM #5: QTY 1, CAT#8055, DESC.: FOCUS ASSEMBLY FOR THE ILLUMINATOR. ITEM#6: QTY 1, CAT#8059, DESC.: SUBSTAGE CONDENSER WITH TURRET. ITEM#7: QTY 1, CAT#8058, DESC.: STAGE ASSEMBLY (MICROMANIPULATOR). THE FOLLOWING ADDITIONAL INFORMATION IS FURNISHED FOR THE ACCESSORIES: THE MICROSCOPE SHALL MEET OR EXCEED THE FOLLOWING REQUIREMENTS: (1) THE ASSEMBLY REQUIRES AN EXTREMELY STABLE VIBRATION FREE OPTICAL BENCH. (2) THE MICROSCOPE SHALL HAVE MAXIMUM LIGHT THROUGHOUT TO AVOID PHOTO DAMAGE AND PHOTO BLEACHING OF CELLS DURING MEASUREMENTS. (3) THE MICROSCOPE SHALL HAVE ALL NECESSARY ADAPTERS TO ACCEPT THE NORAN CONFOCAL ASSEMBLY CURRENTLY OWNED BY THE GOVERNMENT. (4) THE MICROSCOPE SHALL BE MOUNTED ON A VERTICAL OPTICAL BENCH. TO ACHIEVE THE ABOVE REQUIREMENTS THE MICROSCOPE SHALL HAVE THE FOLLOWING SPECIFIC DESIGN SPECIFICATIONS: THE OPTICAL BENCH SHALL BE VIBRATION ISOLATED AND SHALL HAVE LINEAR TOLERANCES BETTER THAN 40UM/METER; THE MICROSCOPE SHALL HAVE INFINITY CORRECTED OPTICS AND PROJECT THE IMAGE WITH NO OTHER OPTICAL ELEMENTS OTHER THAN A SINGLE TUBE LENS AFTER THE OBJECTIVE. THIS LENS SHALL PROJECT THE IMAGE AT THE REQUIRED DISTANCE FOR THE EXISTING NORAN CONFOCAL ASSEMBLY. THIS SHALL PROVIDE THE CAPABILITY THE MEASURE FLUORESCENCE AT LOW LIGHT LEVELS AS WELL AS IMAGING USING TRANSMITTED LIGHT; THE OPTICAL BENCH SHALL HAVE ALL NECESSARY ADAPTERS TO ENABLE COUPLING TO THE NORAN ODYSSEY CONFOCAL MICROSCOPE; THE MICROSCOPE SHALL BE MOUNTED ON A VERTICAL OPTICAL BENCH ON THE VIBRATION ISOLATION TABLE IN THE UPRIGHT CONFIGURATION; THE INSTRUMENT SHLL HAVE FACILITIES TO PROVIDE DUAL PORT ILLUMINATION FROM A MERCURY ARC LAMP AS WELL AS THE CAPABILITY FOR TRANSMITTED LIGHT MICROSCOPY; AND, ALL OPTICS SHALL BE CONSTRUCTED IN SUCH A WAY TO PREVENT LASER LIGHT LEAKS WHEN THE CONFOCAL ASSEMBLY IS TURNED ON. ALL RESPONSIBLE SOURCES MAY SUBMIT A WRITTEN QUOTATION, WHICH, IF TIMELY RECEIVED, SHALL BE CONSIDERED BY THE AGENCY. WRITTEN QUOTATIONS WILL BE DUE NLT 27 SEPTEMBER, 1995 WITH AN ANTICIPATED AWARD DATE OF 29 SEPTEMBER, 1995. (0254)
