UIS2 optics provide high transmission factors for clear, flat images

In the UIS2 optical system, improved transmission factors and compensation for chromatic aberration over a wide wavelength spectrum are not only characteristics of the objectives, but also of image forming components such as the trinocular tube and video camera adapter. As a result, images at all magnification levels are flat, sharp, clear and free from color shift.

Even illumination to the edge of the visual field

Using an original transmitted light diffusion simulation technology, Olympus developed a diffusion optical device which provides bright, even illumination from low to high magnifications.

Excellent color reproduction from daylight illumination

Since Olympus microscopes apply ideal color temperature at natural daylight (5500K) throughout the light source, the objectives and the CCD camera, the camera captures color information accurately and provides faithful reproduction on the display.

Optimal trinocular tube for digital imaging

The high sensitivity of a digital camera allows photos to be taken in about half the light required by a conventional film camera. To optimize digital photography during an observation, Olympus' new trinocular tube U-TR30NIR provides a choice of three light path exchange levels: 100% for binocular, 100% for camera, or 50% each for binocular and camera. This enables photo images equal in brightness to the observation image to be captured on the CCD surface.

Microscope digital camera/ DP71

High-resolution digital images equivalent to 12.5 million pixels captured in approx. 3 seconds — from brightfield to fluorescence.
Thanks to its high-speed hardware, the DP71 can capture high-resolution images equivalent to 1.25 million pixels in around 3 seconds. The camera's high sensitivity and low noise (equivalent to the level of ISO 1600) ensure clear fluorescence imaging, while the resolution quality allows precise representation of particular specimen areas.

By shifting the pixels of the 1.45 million pixel 2/3 inch CCD (one pixel = 6.45µm), it is possible to record still images equivalent to the maximum image recording size (4080X3072) or effective image size of 12.5 million pixels.

Imaging software (for DP71) / DP-BSW

DP-BSW is a user-friendly image capturing software package with a simple, easy-touse GUI (Graphical User Interface) and high speed live display. It can be used to control different types of motorized units, and to perform both still time-lapse image and live image movie recording.

• 

  Intuitive, easy-to-use GUI. Tool bar items can be user-customized and menu icons restricted to frequently used functions.
• Comments with arrow, time and scale can be stored with individual images.
• Focus indicator function shows overall image focusing status; line profile function enables detailed focusing on selected areas.
• Three different metering areas (30%, 1% and 0.1%) can be selected, and moved over the specimen as required, allowing highly precise exposures. A spot centering button is provided to locate and highlight the center of the image.
• In simple time-lapse image mode, the shutter can be opened/closed before/after the exposure by synchronous use of a UNIBLITZ shutter (made by Vincent Associates) or Olympus shutters for the BX61.
• Recorded images can be stored in AVI or MPEG-1 formats, for intermittent shooting of still images or "movie" recording of live images.
• Separate color/grayscale images captured for each excitation wavelength in a multi stained specimen can be combined in layers to create a single composite image.
