Optogenetics catalog
| |
| February 2013 catalog released, featuring our new products: M2 cannulas, 2x2 fiber-optic rotary joints. |
|
Fiber-coupled light sources
| |
| The fiber optic circuits are driven by light and hence the need to couple
the light sources into the optical fiber. The most common sources used to
couple the light into the fibers are the laser diodes and LEDs, while the
miniature incandescent lamps are used only when broad and smooth
spectrum is needed. The incandescent lamps can be used as primary
sources from which different spectral bands and profiles can be extracted. |
|
Splitters/Combiners
| |
| As fiber optics is finding wider use in microscopy, optogenetics and life sciences in general, it is becoming increasingly popular to use wavelength and intensity division or combination of the light within fiber optic circuits. |
|
NA converter
| |
| The Lagrange invariant can be defined as a product of numerical aperture and diameter of the optical fiber. With a lens system that re-images the light from one fiber end to the other, one can change the light cone converging toward the other fiber (NA) and create different spot size.
However, the product of NA and spot diameter or Lagrange invariant remains the same as its name implies. |
|
Connectorized U-Bracket
| |
| Sometimes it is necessary to attenuate the light signal or to filter its spectrum within a fiber-optic link. A simple connectorized U-bracket allows setting the desired intensity attenuation or spectral filtering by inserting the appropriate mini filter from the mini filter set. |
|
Fiber-optic Rotary Joints
| |
| Fiber-optic rotary joint (old name commutator) allows for free rotation of fiber while maintaining excellent coupling efficiency. The device consists of two
collimators mounted on high quality ball bearings that ensure good coupling efficiency while optical fiber is rotating. |
|
Electrical Rotary Joint
| |
| The electrical rotary joint with the through hole is optogenetics-ready if its through hole diameter is larger than the diameter of fiber-optic connector on either end of the patch cord that connects fiber-optic rotary joint and fiber-optic cannula implant. If this is the case, the electrical and fiber-optic rotary joints can be used in tandem. With this in mind, we have developed passive electrical rotary joint with low torque of 0.9 mNm and 1.8 mNm for 6 and 12 electrical contacts respectively that can be used either purely for electrophysiology, or, when combined with fiber-optic rotary joints, for electrophysiological recordings of optogenetically induced events.

Hybrid Rotary Joints
| |
| To better understand the flow of ions in biological tissue or within a single cell, the scientist use electrophysiological recordings to monitor optogenetically marked and stimulated tissue while administering various liquids to the observation site. For in-vivo experiments, one needs the hybrid rotary joints that combines some or all functions of the fiber-optic, electrical and liquid rotary joints within one instrument. For us, each of the possible combinations of these functions is a product category on its own. |

Connectorized Mechanical Shutter Adapter
| |
| Great news for users of laser shutter systems: Add-on connectorized mechanical shutter adapter for SR475
The modulation of light signal is very important for optogenetics experiments. The light sources, like LEDs or laser diodes are well-suited for direct electrical modulation, while some laser types require external modulation via mechanical shutters or acousto-optic modulators. |
|
Fiber-optic cables for optogenetics
| |
| A fiber-optic patch cord connects two distant fiber optic ends and uses the same type
of fiber and connections as the tips of the respective fibers it connects. In the context of
optogenetics experiments with the rotary joint, a fiber optic patch cord is needed to connect
the light source and the rotary joint and yet another patch cord to connect the rotary joint and
the fiber-optic cannula. |

Stereotaxic holders and adapters
| |
| To simplify the implantation of the cannula and maintain the
precision, we have developed stereotaxic cannula holder and fiber-optic cannula
adapters for attaching our cannulas to the stereotaxic arm. |
