Modular and Highly Efficient

The design of this detector unit is unique as it integrates the scanning unit, tube lens and pupil projection lens into a single compact unit. Use of the microscope fluorescence illuminator light path ensures the highest coupling efficiency without limiting the expandability of the microscope itself. Visible, UV and IR laser introduction ports are featured.

New High Reflection Silver Coated Scanning Mirrors

Anti-oxidization silver coating ensures durability and improves reflection efficiency in both excitation and emission with the set of two galvanometer scanning mirrors, increasing the reflectance in the visible range by 5 - 15%, and IR reflectance up to 22%.

Original Spectral System

The original spectral detection system features two independent spectral detection channels, each configured with a diffraction grating and variable slit for high resolution wavelength separation and high speed bandwidth selection. Accurate spectral unmixing of overlapping fluorescence emissions becomes possible with a linear resolution of 2 nm throughout the visible spectrum (400 to 800 nm). Two different spectral deconvolution algorithms – normal and blind deconvolution – allow an easy and fast separation of different but overlapping fluorochromes within the specimen. High speed spectroscopy can be performed at a maximum speed of 100 nm/msec.

Variable Barrier Filter (VBF)

With the spectral detection system, the ideal wavelength spectrum is automatically selected once a fluorochrome combination has been selected using the software. Manual adjustment of the wavelength range is also possible according to the fluorescence emission wavelength peaks.

Speed at High Precision

The incorporation of highly stable galvanometer scanner mirrors and an Olympus original acceleration circuit enables high-speed imaging of 16 fps for a 256x256 image format or 38 fps for smaller image formats.

Tornado Scanning

Conventional raster scanning cannot always complete the photobleaching process quickly. The unique Tornado scanning ability of our SIM unit makes the procedure much more efficient and significantly reduces the necessary bleaching or activation time.

Laser Power Monitoring

Laser light intensity is monitored and fed back to the acousto-optic tunable filters (AOTFs), helping to stabilize the excitation light during long-term (overnight) time lapse imaging.

High-performance Multi-alkali PMT

Special high performance multi-alkali PMT selection in this scanning unit ensures high detection efficiency using reliable and well-proven PMT technology.
