DIATOM TEST SLIDE of Micromanipulated Pinnularia dactylus var. dariana (A.Schmidt) Cleve
Details to detect: poroids
The theoretical limit of resolution of most light microscopes is ∼ 0.2 μm, but these poroids can be detected by the techniques below, thanks to Diatom Cubed high refractive index mountant!
Viewed with SEM, QUANTITATIVE FEATURES in Diatom Lab's sample are:
Poroids inside the striae: 44 - 45 in 10 µm
Average distance between poroids: 0,072 - 0,089 µm. See SEM image from the same sample!
(While In Amphipleura pellucida striae number 37-45 in 10 µm and pores are spaced 0,16 - 0,19 µm apart)
Recommended microscope objectives: Oil-immersion 63 or 100x objectives having a very good or excellent numerical aperture (1,3 or 1,4);
Suggested techniques to detect the poroids: Double immersion (= Oil immersion objective and Oil immersion condenser) with Polarized light (the polarizers should be oriented perpendicular to each other = maximum level of extinction) and possibly oblique illumination; or Immersion dark field condenser (better 1,2/1,4) with Polarized light (the polarizers should be oriented perpendicular to each other = maximum level of extinction)

Recommended microscope objectives: oil-immersion 63 or 100x objectives having a very good or excellent numerical aperture (1,3 or 1,4)
Suggested techniques: Double immersion (= Oil immersion objective and Oil immersion condenser) in: Polarized light (the polarizers should be oriented perpendicular to each other = maximum level of extinction) with possibly oblique illumination; or Immersion dark field condenser (better 1,2/1,4) with Polarized light (the polarizers should be oriented perpendicular to each other = maximum level of extinction)

Optical Aberrations Detector for transmitted light (with cover glass and mountant).

Optical Aberrations Detector for reflected light (without cover glass).

For transmitted light (with cover glass and mountant). Diatom Lab CENTERING DEVICE & MICROMETER GLASS SLIDE is an all-in-one microscope slide that incorporates a centering device to center the microscope and the camera and a stage micrometer for microscope calibration. The centering device consists of 25 perfect concentric circles, 50 µm (fifty micrometres or microns) thick and 50 µm apart! It is very useful to center the microscope parts (condenser top lens, field iris diaphragm, prisms of the binocular/trinocular head, etc.) and the microscope camera. The stage micrometer for microscope calibration is a 1 mm Scale with 0,01 mm (10 µm) divisions. The slide can be used in combination with a micrometer eyepiece or a measurement software (for cameras) in order to measure preparations.

10 selected, micromanipulated Radiolarians for Scanning Electron Microscopy (SEM), micromanipulated and fixed on microscope slide without cover glass and mountant in this case. Radiolarians are fixed by means of the proprietary Diatom Lab's NANO-ADHESIVE, which is invisible to scanning electron microscopes and is therefore used to obtain a clean background for our SEM specimen preparations!

Very small integrated circuit (0.75mm X 0.66mm) with many fine details, dry mounted on microscope slide without cover glass. Excellent for testing light microscopes in reflected light, stereo microscopes, scanning electron microscopes (SEMs), objectives for macro photography! This test integrated circuit has been discussed in the following article: Walker D., Exploring the Diatom Lab prepared slide of an integrated circuit chip, Micscape Magazine, April 2020, Issue 289, ISSN 1365 – 070x: "The slide is impeccably prepared / mounted", "In my view the slide is excellent value for money and maintains the high standards set by the Diatom Lab shop (I have a number of the diatom slides)"
