Buying Guide

Match magnification to your use case

Choose 10x eyepieces for general viewing, 40x or 100x objectives for higher detail; combine eyepiece and objective magnification to reach desired total power

Check optical design (achromatic vs widefield)

Achromatic objectives correct color for basic lab work while widefield eyepieces provide a larger, flatter field for comfortable observation

Confirm mounting diameter and compatibility

Verify eyepiece barrel size (e.g., 23.2mm or 30.0mm) and objective thread/holder type so the lens fits your microscope or C‑mount camera

Prioritize build quality and coatings

Look for multi-coated optics and metal housings for better contrast, durability, and reduced reflections in bright or digital imaging setups

Consider digital imaging needs

For camera use, choose C‑mount lenses or objectives with known CCD compatibility to avoid vignetting and ensure correct sensor coverage
