直径37ミリとのことで半世紀前のオリンパスシステム顕微鏡と互換性ありと思い込みましたが違いました。(大昔の日本の顕微鏡は世界規格で製造されていました。）百均ノギスでは同寸ですがこの製品、極僅か太いので適当に合致するまで削りました。見栄えは悪くなりましたが実用になりますので良しとしますが次購入する時は注意します。観察結果写真は全て対物レンズの直接焦点画像、接眼レンズは使用していません。(対物レンズ10倍・20倍・40倍を使用）観察物は「つくしの胞子」プレパラート封入剤は水、水の蒸発防止にカバーガラス周囲にグリセリン塗布効果絶大！オリンパスE型システム顕微鏡使用(1956年頃発売）光源LEDに改造。★追記 手元にオリンパスSIFL100という絞り付きの対物レンズがあるので試用してみたら絞り操作で暗視野効果が得られました。（画質はあまり良く有りませんが・・・）(つくしの胞子が一番大きな写真）

J'ai pu tester ce filtre avec les petits grossissements x40, x80, x100, x150, x200, x250 et la qualité est excellente. Le fond noir est bien noir. La transparence et les couleurs du spécimen que j'ai observé était magnifique. Malheureusement, d'autres problèmes des saletés dans le microscope Amscope T490B, la caméra HC210+ lentille de réduction 0.5 avec rayures ne m'ont pas permis de tester l'objectif 40x avec le dark field dry. Mais en ce qui concerne juste le filtre, il est parfait et d'une très bonne qualité. Je le recommande vivement.

For a very inexpensive darkfield condenser this work well with good edge illumination. The centering knobs balance the illumination smoothly. So far it seems to work best in the 100X to 600X range. There is some flare at 40X but that may be my set-up. Since this is dry (intentionally) I can't try it at 1000X. If you have an old Bausch&Lomb microscope, while they are both 37mm, B&L means the condenser mount is 37mm and AmScope (and I suspect all modern scopes) means the condenser is 37mm and some fitting will be necessary (but presumably not with a new scope).

Ok I i make my own darkfield filters and get great results so I really hoping that 100 dollar darkfield would be amazing.Well a couple of things. First you need to turn you light all the way up. If you are are just viewing 10x-20x is fine.But if you want to film using a camera rig with dslr. This is a no go why? Normally my setting aperture 100 iso 200-400 with this darkfield all you get is a black screen I have to bump it up to 6400 which then is grainy.I would have thought this would have a type of iris to make this darkfield brighter or darker. So for just viewing it’s ok for pro camera setup does not work at all.If you want to know what the 2 silver kob stick are...they are for adjusting just the center.

It is a good condenser for most uses. Very solid, does not disappoint. But as I have used it more and more, I wish I had purchased the one sold by AmScope directly with an iris. hace falta.I don't regret purchasing it, but it will be my backup and not my primary use condenser.

Used for viewing live and unstained slides ..it takes the light from the. Bottom where u are looking at specium with the light going thru .Redirects the light not thru , but from the sides at vairing angles . A must for highly transparent objects.
