NIGHTSEA Model SFA Fluorescence Adapter for Keyence VHX Series Digital Microscopes (continued) Lens-specific solutions


The Keyence lens you are using (not the microscope model) determines how the NIGHTSEA light source and barrier filter will be added to the system. The light source will either placed to the side of the microscope stage or mounted over the Keyence light source input port. The barrier filter will either be slipped over the bottom of the lens or inserted in the Analyzer slot. The options are summarized below.


Lens


FI Head – E20 or E100 VH-Z500


VH-Z50, -Z100


VH-ZST – high mag VH-ZST – low mag VH-Z00, -Z20


VH-Z00, -Z20 Light source – placed to the side of the microscope stage


Barrier filter – slips over the bottom of the lens and attaches with thumbscrews. See at right.


VH-Z50, -Z100


Light source – placed to the side of the microscope stage or mounted over the Keyence light source input port


Barrier filter – inserts in the Analyzer slot at the top of the lens


Z00 and Z20 lenses – the barrier filter slips over the bottom of the lens.


VH-ZST • 20-200 lens


Light source – placed to the side of the microscope stage


VH-Z100 lens light input port with NIGHTSEA adapter and light head.


LHM-Z100 Light Head Mount


Barrier filter – inserts in the Analyzer slot at the top of the lens


• 200-2000 lens


Light source – mounts over the Keyence fiber optic input port (except for UV) providing enhanced performance at high magnification


Barrier filter – inserts in the Analyzer slot at the top of the lens


Z100, Z500, and ZST lenses – the barrier filter inserts in the Analyzer slot at the top of the lens.


VH-Z500


Light source – mounts over the Keyence light source input port


Barrier filter – inserts in the Analyzer slot at the top of the lens


VH-Z500 fiber optic port with NIGHTSEA adapter and light head


NOTE – The Ultraviolet (UV) light source does NOT work well when mounted over the Keyence fiber input at either high or low magnification. Consider our Violet (VI) light source as an alternative for many applications.


VHX-7100 Fully Integrated (FI) Head • VHX-E20 and -E100 Light source – placed to the side of the microscope stage


Barrier filter – inserts in the Analyzer slot at the right side of the FI head


• VHX-E500 and -E2500 Use with these lenses is likely not practical due to short working distance


FI head – the barrier filter inserts in the Analyzer slot at the side of the assembly
