Question
What resolution is the uScopeGX?
Answer
The uScopeGX is wavelength-limited. Image resolution is governed by the wavelength of visible light and depends on the numerical aperture (NA) of the objective and the camera mode: SD (standard definition–960×540) or HD (high definition–1920×1080).
| uScope Model | Objective | NA | SD Pixel Mapping µm/pixel (MPP) | HD Pixel Mapping µm/pixel (MPP) | SD Resolution DPI | HD Resolution DPI |
|---|---|---|---|---|---|---|
| uScopeGX-10 | 10x | 0.25 | ≈0.80 | ≈0.40 | ≈30,000 | ≈60,000 |
| uScopeGX-20 | 20x | 0.40 | ≈0.40 | ≈0.20 | ≈60,000 | ≈120,000 |
Notes
- As a rule of thumb, NA × 1,000 is the total magnification possible with any given objective.
- The formula to convert MPP to DPI is: DPI = (25.4mm ÷ 1 inch) × (1,000µm/mm ÷ MPP)
