High NA Fiber Optics for In-Vivo Optogenetics – The Options on Goldstone Scientific

Posted by

Quality fiber optic implants are crucial for successful in-vivo Optogenetics. Scientists will need to spend time or money (or both) to ensure quality results. Prizmatix offers a range of options and Goldstone Scientific makes it easy to order and offers competitive prices with bulk discounts and fast shipping to save you both. Many items are in-stock and ready to ship from our Michigan office.
Call us directly at 248-424-9390 if you have any questions about availability and ordering.

Here are the options you can choose from:

Ready Made Implants
Would you rather not bother making your own? Our ready-made cannulae are machined cleaved and polished for excellent quality and uniform results. A 15% discount is applied to orders of 20 or more implants, 100 or more are 25% off for even greater savings.

Uncleaved cannulae (Pack of 20)
Save time and money with these pre-assembled and polished cannulae. The fiber is pre-installed in the ceramic ferrule and the flush side is machine polished. All you have to do is cleave to the correct length. These are a great choice when you are not sure yet of the protrusion length that you will need.

Precleaved Fibers (Pack of 20)
Cleaving optical fibers is not easy, and imperfect cleaves will affect the power output of the fiberoptics. Our pre-cleaved fibers save you the hassle of cleaving and inspecting. All you have to do is glue the fiber into an empty ferrule and polish the flush side.

Raw Fibers & Empty Ferrules
For do-it-yourselfers. Our fibers have very high NA of 0.63 or higher and come in packs of fifty 10-12cm segments. We offer a variety of core diameters that allow you to take advantage of higher power that LEDs deliver with larger fibers.

Our High NA optical fibers are LED and laser compatible. For more information about NA and how crucial it is for LED light sources see our blog posts  here and here.

Bulk discounts start at 10 packs and are as much as 20% off.
Core diameters we offer: 100um (NA=0.37) and 200, 250 (NA=0.66) and 500um (NA=0.63)
Our ferrules come in packs of 10 and can be uses with raw or pre-cleaved fiber.
Our standard 2.5 and 1.25mm sizes are competitively priced with discounts starting at 10 packs.

Hole diameters are:
230um for 200um fibers
290um for 250um fibers
510um for 500um fibers (special order, call for availability and lead time)
100, 200, 250, and 500um core with NAs as high as 0.66.

Light Meters, Fiber Optics and Optogenetics – Part 2 – Bad Detector Advice

One of our customers was recently shopping for a light meter and detector. I had recommended a particular meter and a detector with a silicone photodiode from a popular vendor. The vendor advised that a detector with a thermal sensor would be better for an LED light source.Our engineers looked at that sensor, and advised it would [...]

High NA Fiber Optics and Collimators; Don’t Shoot Yourself in the Foot

A customer recently complained that the power output of her Prizmatix fiber coupled LED was too low. The LED system was 5 years old and she suspected that the power loss was due to age. She wrote: I'm using a  Prizmatix FC8-LED fiber coupled multi-channel LED source, along with a fiber that we purchased from you. This fiber is attached to a custom-made [...]

Prizmatix Fiber Optic Rotary Joint; Compatibility of with Lasers or other light sources

The Prizmatix Fiber Optic Rotary Joint is an important part of the Prizmatix  In-Vivo Optognetics Toolbox. It’s extremely low torque (<10μNm) allows even the smallest animals to move freely and its high transmission is helpful in getting as much power as possible to the target. One really nice feature of the Prizmatix fiber optic rotary joint is that it can be used [...]

Do LEDs have enough power for In-Vivo Optogenetics?

Do LEDs have enough power for In-Vivo Optogenetics?  It depends who you ask. Often, while talking to researchers considering LED for Optogenetics, I hear “People tell me that LEDs just don’t have enough power, especially for inhibition”. That is a real concern. In fact a competing vendor of LEDs for Optogenetics told me that their light sources do not have enough power, [...]

​Extra Long, Flexible Fiber-Optic Implants for Optogenetic Stimulation of Peripheral Nerves

While at SfN 2015 in Chicago quite a few people that stopped by the Prizmatix booth asked how they could optically stimulate neurons in parts of the body far from the brain. One researcher explained that due to the NIH’s SPARC program, there is an increased interest in researching peripheral nerves. Their plan was to implant a ferrule in [...]
