Lehrmittel XXL 934,92 EUR Wellenwanne PM02 1, 2, or 3 Are they all equal?
Lehrmittel shop 827,05 EUR Artikelnummer: GA 45740 Cornelsen Experimenta 1, 2, or 3
[1] Conatex 1057 EUR Artikelnummer 1077054 CONATEX Lernsysteme 1, 2, or 3
  • Justification: The concept of waves including understanding of constructive and destructive interference is very important for optics. In fact, to understand this concept is essential for full understanding of image formation in a microscope.

A wave tank (in German "Wellenwanne") allows to show these concepts very descriptively using water waves. Usage of such a wave tank for our basic microscopy course would thus be a very beneficial asset.

Ivo haas [3]

  • Optik magnethaftend, #47095, 499,80EUR
  • Gruppensatz Spektroskope, #47385, 29,75
  • Stichgitter 600 lines/mm, # 47283, 32,55
  • Stichgitter 1200 lines/mm, # 47284, 32,55
  • If all prices stay below 500EUR, just get 1 offer.
  • Justification: PLEASE fill in a few lines

Pete and Sebastian

  • Ideas:
    • Wicked laser Nano ($69.95 USD 3 available colors 405nm/75 mW, 532 nm/15 mW, and 650 nm/100 mW) with a
    • Lens kit ($29.95 USD - comes with line/sheet adapter)...
    • Laser safety glasses for $19.95 USD each.

Please make up your mind regarding the lasers and the lens kit Pete suggested. If you manage, provide offers as usual:!

  • Price > 500EUR -> PLEASE provide three offers
  • Justification: pending
  • Pete:
    • diffraction demo would be great
    • laser could be used by Davide as well for interferometer (update: we step back from the home made version, no need for lasers anymore)
  • Sebastian:
    • laser safety needs to be considered
    • safety glasses will prevent people from seeing the light
    • let us plan it in detail and get it later since the price is not incredibly high

Davide

Interferometer

  • three offers needed since price >500EUR
Comparison Mach-Zehnder-Interferometer offers
manufacturer price features rating comment
LD DIDACTIC 5343,46 EUR 632,8nm laser, others? 3 offer by Sebastian
Thorlabs 2119,54 EUR ? 1 offer by Sebastian
Dr. Martin Henschke - Gerätebau 3199,91 EUR ? 3 laser currently sold out
  • Justification: The interferometer is an extremely precise instrument that allows to demonstrate the wave nature of light. In addition, the kit provided by Thorlabs gives the possibility to manipulate the optical path allowing different experimental experiences ranging from the measurements of the refractive indexes of different materials to the complete black out of the final image due to destructive interference.

Thomas Kurth

  • EPON-Kit kostet: 80,40€
  • 10 x 5ml 4% Osmium: 181,50€.

Material will be brought by CRTD since it is for the BioRegMed course.

  • Price > 500EUR -> PLEASE provide three offers
Comparison voting kit offers
manufacturer price features rating comment
Adidact RF-NXT 1994,44 EUR 30 devices 1 multiple choice, text, numbers, sorting
Adidact RF-LCD 1655,29 EUR 30 devices 3 multiple choice
Intellididact 2388,21 EUR 30 devices 3
PowerVote 2995 EUR 30 devices 3 case for the kit is extra
  • preference: Adidact offers, because of the lowest price; of these two the offer with RF-NXT response cards would be preferred, because it offers additional functionality over the RF-LCD (in addition to multiple choice there is the possibility of typing text and numbers and do sorting, which makes the system much more versatile)
  • Justification: Teaching microscopy courses is an integral part of the BioDIP activities. The curriculum is updated regularly. However, we have noticed that it remains a challenge to collect comprehensive and accurate information concerning knowledge transfer. An interactive audience feedback system is a very capable solution to do exactly this. It would enable us to tune and adapt our courses in the parts where it is really necessary. At the same time such system can also be used for feedback rounds with students.

Silke T

  • Dino Lite Digitale Mikroskopkamera [4]
  • USB connection to PC
  • Price > 249,00EUR
  • Justification: simple and easy way to connect a microscope with a computer, beamer, etc. --> teaching, presentations

Isabel and Hella

  • Laptop for teaching and seminars (around 1.500 EUR)
    • Ralf takes care of an offer
  • BioDIP flyer (300EUR)
