🔧 Product Description

The Olympus SZX2-CDF is the dark field cartridge designed exclusively for the SZX2-ILLTQ transmitted illumination base. Dark field illumination works by blocking the direct transmitted light beam and allowing only obliquely scattered light to reach the objective — the result is a dark background with specimen features rendered in bright, high-contrast relief. This technique is particularly powerful for transparent, unstained, or low-contrast specimens that are nearly invisible under conventional bright field illumination. Fine surface details, edges, particles, and internal structures that scatter light are revealed with exceptional clarity. Installation is tool-free: the cartridge drops directly into the SZX2-ILLTQ cartridge port and can be swapped with other SZX2 contrast cartridges in seconds. Built to Olympus factory specifications, the SZX2-CDF ensures consistent optical performance and a guaranteed fit with no realignment required.

🔎 Typical Applications

• Live cell and aquatic biology — visualizing transparent organisms, larvae, and embryos without staining
• Particle and contamination analysis — detecting fine particles against a clean dark background
• Entomology and botany — revealing fine surface and edge detail on transparent or semi-transparent specimens
• Electronics and materials inspection — detecting surface defects, cracks, and inclusions
• Multi-contrast SZX2 workflows where dark field and bright field cartridges are swapped as needed
