magnification

Voorbeeldzinnen

1. This microscope has a 100X magnification.
2. Stereomicroscope (minimum 40' magnification).
3. Low magnification examination to assess the sample
4. magnification of objective (100 ×, 40 × etc.).
5. Compound microscope (minimum 400' magnification), transmitted light or polarised light.
6. This magnification value is indicated for 3 µm fibres, for 6 µm fibres a magnification of × 5000 may be more suitable.
7. Scanning electron microscope capable of resolving down to 10 nm and operating at × 10000 magnification.
8. Observe the slides immediately with a microscope fitted for epifluorescence microscopy at 630 or 1000x magnification under immersions oil.
9. Observe the slides immediately with a microscope fitted for epifluorescence microscopy at 630 or 1000 × magnification under immersion oil.
10. Initially the sample should be examined at low magnification to look for evidence of clumping of large fibres and to assess the fibre density.
11. Examine test slides on an epifluorescence microscope with filters suitable for excitation of FITC, under oil or water immersion at a magnification of 500-1000.
12. The optimum fibre density should give an average of about one or two countable fibre per fields of view at 5000 magnification.
13. The fibre diameters are measured at a screen magnification of × 10000 or greater [1] using a line intercept method to give an unbiased estimate of the median diameter.
14. Examine the stained smear with an epifluorescence microscope at 450 nm under oil immersion at a magnification of 600 to 1000 using an oil- or water-immersion objective.
15. Lower magnification may be used if the material does not contain small (diameter) fibres and the fibre diameters are large (> 5 μm).
