AmScope LED-144-YK 144-LED Microscope Ring Light with Adapter

Enjoying the light while inspecting solder connections on PCB boards.

J'utilise pas mal de produits liquide sous le microscope et j'en arrive à la sécurité de l'ensemble; En effet, ce produit est douteusement conçu, il présente une fuite de courant alternatif sur la masse de la prise Mini-USB (qui d’ailleurs produit 12V, on croit rêver) ne surtout pas s'en servir de chargeur! les 144 Leds sont divisées en quatres canaux, mais shuntés entre eux... pas de modulation, ça risque de ne pas tenir longtemps tout ça, je ne rentrerais pas dans plus de détails, les Leds font leur boulot mais ce boitier de commande est une honte pour ce prix et potentiellement dangereux de surcroît, j'utiliserais un vrai pilote de rétro-éclairage en classe III à la place.

I have the SM-2TZZ scope and needed to get very high resolution on nano samples we are testing. The light on the scope just does not work well at the resolution level. The SM-2TZZ has a 1X and 2X lens at the base and this unit sits nicely over the 2X and it has an adapter for the 1X. The light has 3 set screws which are easily tightened and released and the control allows for great adjustment of light intensity from the LEDs. I can get what I need at highest resolution and the ring does not interfere with the scope and its allows for relatively even coverage of light intensity. The color adjustments are simple using the AmScope White adjust which you must use every time. Good price, great quality.

Hip hip !!!

Works great. Provides clear white adjustable lighting just above the target field. Best part is the continuously adjustable intensity controlled by a regular potentiometer (versus incremental push button style). Easy to find the best illumination for the sample analyzed.
