Light Head Hanger

Description

How does this work?
The extension cables plug into the gooseneck lamp base and can bring power to either one or two light heads.

Single light head and cable	Two light heads with dual cable

The Light Head Hangers mount to the end of any of the thumbscrews on the SFA adapter ring. They are available in long and short pivot arm versions for use with long and short working distance microscopes.
– Long working distance (LWD) – 6.5 cm (2.5 in.) and greater
– Short working distance (SWD) – 6.3 – 4.6 cm. (2.5 – 1.8 in.)

What is the benefit?

There are two main potential benefits with this new accessory:

Increase excitation intensity without buying a second lamp base
Until now if you wanted to increase the fluorescence excitation intensity of the SFA system you would need to buy a second light head and lamp base. This would take up additional real estate on your laboratory bench. With the Light Head Hanger system you can power two light heads from one base and mount them both directly to the NIGHTSEA adapter ring.

“We had some issue detecting red fluorescent proteins with some of our weaker transgenic zebrafish lines, but by shining two LED lights onto the same embryo, most of our weakest GFP and mCherry transgenic lines can now be detected. One light head was fine for reasonably bright specimens, and with two lights, the fluorescence is nearly the same as traditional stereomicroscopes priced $15-20K.”

Reduce the chance of accidentally bumping the light
Taking the light head off the gooseneck and mounting it directly to our microscope adapter reduces the chance of the light head being bumped so that it is not illuminating the subject on the microscope stage to best effect. This might be especially valuable if you are using the system for outreach demonstrations and multiple people will be working around the microscope.
