Measurement Method: Interleaved Method (when using 2 or 3 wavelengths) Multiple wavelength LED light sources are pulsed in sequence, and the fluorescent signals corresponding to those emission wavelengths are captured by a CMOS camera. Number of Measurement Channels: Up to 9 ROIs can be measured simultaneously (when using a 200μm core diameter optical fiber). This allows for the observation of multiple animals at the same time, or the simultaneous observation of multiple locations on a single animal.

The dual optical fiber cannula is a type that accommodates two optical fibers in a single receptacle. It is used for applications that require stimulation/inhibition at two symmetrical or simultaneous locations. The spacing and insertion depth of the two optical fibers are specified and confirmed during manufacturing, which helps resolve issues such as limitations in spacing distance and increased positional errors that can occur when using two single-core optical fiber cannulas. We offer two types: one with a guide socket for secure connection and another with guide pins. Corresponding patch cords (DFP: Dual Fiber-optic Patch Cords) are also available for use with them.

One method for observing neuronal activity under free behavior is the head-mounted fluorescence microscope. The microscope body weighs only 3 grams and is equipped with a CMOS sensor, an electronic focusing mechanism (focal depth 0-300μm), and filters. An imaging cannula (GRIN lens) is inserted into the animal's head, capturing images at the lens tip with the CMOS sensor. This model adds a light stimulation function (optogenetics): NpHR halorhodopsin activation capability to the aforementioned features. The microscope body and the imaging cannula (GRIN lens) are securely and easily fixed with screws, and no special fixtures are required for fixation. Four types of imaging cannulas are available, depending on the depth of the target to be observed and the diameter of the GRIN lens. By using an imaging cannula equipped with a prism at the tip, it is also possible to observe sagittal or coronal sections.

The OASIS Implant is a fluorescence imaging fiber scope that responds to light stimulation in any area under free movement. Unlike typical head-mounted micro-fluorescence microscopes, it houses optical devices such as cameras and filters for calcium imaging on a platform body separate from the animal. This reduces the weight burden on the animal's head and allows for the use of higher resolution cameras. All equipment that can be attached to the platform body, including cameras, light sources, and filters, is interchangeable, enabling observations using different fluorescent proteins with a single device.

The optical fiber output visible light semiconductor laser source is used as a light source for optogenetics and fluorescent lighting. There are different types of lasers, and the semiconductor laser is called LD: Laser Diode. The semiconductor laser source manufactured by Doric has the laser oscillation resonator inside the semiconductor chip, allowing visible light to be emitted directly from the resonator. Therefore, it can achieve very stable output even with high-frequency pulse oscillation. Additionally, there is no concern about output reduction due to alignment shifts. Since the laser light source has a very narrow linewidth, the optical fibers used typically have an NA of 0.22 and a core diameter of 200 μm. Optical fiber core diameters starting from 50 μm can also be used.

The optical fiber output LED light source is the easiest light source to introduce for optogenetics and fluorescent lighting. Due to its wide wavelength range (bandwidth) and uniform irradiation intensity, it is excellent not only for optogenetics (light stimulation) but also as a light source for fiber photometry and head-mounted fluorescence microscopy, and is widely used. The LED light sources from Doric, a lens manufacturer, boast high fiber coupling efficiency and feature a diverse lineup, including combined types that integrate multiple wavelengths and types that are integrated with rotary joints. The output of the LED light source varies depending on the core diameter and NA of the connected optical fiber patch cord.

Spotlight LED Light Source: The PLS series is an LED light source with a uniform power distribution in the irradiation area. By combining high-output LED chips with aspheric lenses, it achieves a uniform power distribution across the entire irradiation area. The standard range model can be used at a working distance of 100mm or more. As the working distance increases, the beam diameter also increases, but a uniform power distribution can be obtained. The close range model can be used at a working distance between 75mm and 100mm. Please note that if you go outside this working distance, a uniform power distribution cannot be achieved.

In neuroscience, fiber photometry is a method that involves an embedded optical fiber that illuminates neurons tagged with a fluorescent calcium indicator with excitation light and detects the fluorescence emitted from their activity for observation and measurement. In fiber photometry, the fluorescence activity of all neurons within the detection range of the optical fiber cannula is captured as a single signal, even if there are multiple active locations.

The optical fiber cannula, essential for InVivo optogenetics, is a component made of a zirconia ceramic or metal ferrule and optical fiber. The tip of the optical fiber is the side that will be implanted. There are diameters of 1.25mm and 2.5mm available. The most commonly used type for insertion into mouse brains has a ferrule made of zirconia ceramic with a diameter of 1.25mm (ZF1.25), and the optical fiber part is of type 200/240-0.22. The length of the optical fiber part can be specified in 0.1mm increments depending on your application (tolerance is <0.1mm). Additionally, multiple shapes of the optical fiber tip are available depending on the type of light diffusion. This optical fiber cannula connects to a patch cord via a sleeve, allowing light from the light source connected to the patch cord to be irradiated onto the brain or biological tissues. The zirconia ceramic version is recommended as it is lighter and places less burden on the organism compared to the metal version.
