Condenser sliders are used to improve illumination under certain conditions and several are available for the EVOS imaging systems, including a diffuser slider, pinhole slider, and meniscus sliders. Due to variances in sample size, color and thickness, actual slider use may differ from suggestions. This pinhole slider is intended for brightfield applications at all magnifications to enhance contrast. Note that the pinhole condenser slider is included with the EVOS FL and FL Color imaging systems.
