Uniform Illumination with Consistent Color Temperature
The CX43/CX33 LED illumination provides several advantages, both immediate and over the long-term:
Produces daylight conditions so specimens can be viewed with their natural colors
Consistent color temperature at any brightness, so can avoid spending time making adjustments when you change the brightness
A long 60,000-hour lifetime with the brightness level remaining stable throughout
Fixed Köhler Illumination for Comfortable Viewing

CX43 and CX33 microscopes provide fixed Köhler illumination, enabling you to achieve the right illumination without adjusting the condenser.
Remain Comfortable during Extended Usage

Ergonomically Positioned Focus Knob
The low-positioned focusing knob enables you to conduct your observations while keeping your hands and forearms in comfortable positions resting on the desk. When working under high magnification, the focusing stopper prevents a specimen from accidentally hitting an objective.
Ergonomic Stage and Eyepiece Position
CX43 and CX33 microscopes offer features that support you through long hours in the lab:
Low-positioned stage to enhance comfort and reduce fatigue
Stage visibility from the eye point position to enable you to smoothly set and check specimens
Low stage knob that can be controlled with just a light touch, so you can quickly and comfortably view your specimens

Excellent Optical Performance for Flat Images
CX43
CX33
CX43 and CX33 microscopes can be used with plan achromat objectives, which provide clear images with high image flatness over a wide field of view. You can view specimens clearly with even illumination during routine observations.
*The CX43 is compatible with all UIS2 objectives while the CX33 comes with specially designed plan achromat objectives.

Supports Up to Five Objectives
CX43
For added flexibility, up to five UIS2 objectives can be supported on the revolving nosepiece. In addition to general objectives, you can select a 2X objective for wide area observation or objectives for phase contrast.
