DescriptionSpatially patterned illumination with temporal and spectral control enables numerous new techniques in life-science applications such as optogenetics. For example, in optogenetics, selected neurons in a specimen slice can be activated or silenced with a user defined illumination pattern.
Mightex Polygon400 multi-wavelength dynamic spatial illuminator (DSI) integrates the state-of-the-art spatial light modulators and high-power LEDs using a proprietary Etendue-preserving optical design to deliver high-intensity illumination patterns with diffraction-limited resolution. A Texas Instruments’ DLP spatial light modulator is used to display a user defined image pattern. At the heart of the Polygon400 is a unique optical system that carefully delivers light from LED sources to the DLP panel and then through a microscope to the specimen plane. Such a systematic approach makes it possible to achieve maximum optical intensity while maintaining diffraction-limited imaging performance.
Temporal performance is a key to many intended applications for Polygon400. With a frame rate of more than 4,000 fps and fast-switching LEDs, Mightex Polygon400 can deliver illumination patterns with micro-second precision. Advanced Polygon models with external LED controllers also enable wavelength switching in between illumination patterns at the highest frame rate.
Customers may specify up to three LEDs in the range of 400nm to 700nm to be included in the built-in light source engine. A lightguide-coupled model is also available where any light sources such as LEDs and arc lamps can be used for illumination. Note that the lightguide-coupled model does not have built-in LEDs.
A dedicated software allows users to generate illumination patterns as well as control illumination intensity and timing. The software also supports alignment between illumination patterns and images acquired through any digital cameras on a microscope.
Mightex Polygon400 is designed to be easily inserted into the infinity path of a microscope. For inverted microscopes, the preferred inserting point is usually the back port of the microscope where a fluorescence attachment is commonly placed. A filter cube is required to fold the Polygon400 light path into the microscope. The filter cubes used for fluorescence observation serves this purpose well. For upright microscopes we provide a beam combiner cube to be inserted below the binocular/trinocular unit. The dichroic or mirror in the beam combiner directs the Polygon400 beam into the microscope light path.
