Olympus LCACH 20x PHP Phase Contrast Objective

The Olympus LCACH 20X PHP phase contrast objective is specifically engineered for convenient phase contrast microscopy on Olympus CKX41 inverted microscopes. The PHP (Pre-centered Phase) designation indicates this objective features pre-centered phase rings that eliminate the need for phase ring alignment, providing immediate phase contrast imaging capability. This pre-centered design significantly simplifies phase contrast microscopy setup and operation, making it ideal for routine applications and educational settings. Phase contrast microscopy enhances contrast in transparent, unstained specimens by converting phase shifts in light passing through the specimen into amplitude changes, making cellular structures visible without staining. At 0.40 numerical aperture with 3mm working distance, this objective provides excellent resolution with comfortable clearance for specimen manipulation. The LCACH (Long Chromatic Aberration Corrected) optical design provides good chromatic correction for quality imaging. The RMS thread ensures compatibility with Olympus CKX41 inverted microscope systems. Factory-new condition ensures optimal optical performance and reliable operation for laboratory, clinical, and educational microscopy applications.
