The Phase Contrast Accessory expands the capabilities of your LS Microscope by enhancing visualization of transparent specimens including unstained samples. By using phase contrast, even living cells can be imaged in their natural state with high contrast and sharp clarity. This accessory can also be used to obtain high quality brightfield images.

All Etaluma’s LS Microscopes now use one basic Phase Contrast Accessory that makes use of the Olympus phase condenser. The resulting Phase Accessory attaches easily to the LS Microscope via an adaptor on the back of the Microscope deck.  LS620, LS600, LS520, and LS420 use the same Phase Contrast Accessory.  The LS720 Phase Contrast Accessory has a different arm that attaches to the LS720 on the upper right surface.

Etaluma offers 2 different Sliders containing phase rings that are matched with their objectives.  The Slider with precentered rings (used with IPC objectives) comes with both Phase Contrast Accessories described in the paragraph above.  A second Slider with non-precentered rings (used with PH objectives) must be ordered separately.

The 20x, 40x, and 60x PH objectives offer the advantage of a correction collar and thus can be used with labware having a thickness of 0-2 mm.  The IPC objectives are optimal when imaging through 1 mm of plastic or glass.

Both Phase Contrast Accessories are controlled directly by the LS Microscope via a communication cable. 

Etaluma offers 4x, 10x, 20x, and 40x Phase Contrast Objectives for the precentered Slider and 10x, 20x, 40x, and 60x Phase Contrast Objectives for the non-precentered Slider (see Objectives).  Both types of Objectives provide high quality phase contrast images and also excellent fluorescence images, making them very versatile.  Additionally, very good brightfield is achievable using either Phase Contrast Accessory because the transmitted light coming from the overhead condenser is collimated (parallel rays).
