Re: HA2307 HDMI industrial camera

The problem being it does not deliver full resolution via usb. It is good to hear a first hand account of using one. Specs are one thing but it's hard to know how it will handle without trying it. If thats the case, usb would be a show stopper. Thanks all for the software tips, I may check it out j...

Re: HA2307 HDMI industrial camera

I have to say after living with this camera for several weeks, I can not wait for my Nikon to come back. The thing that bothers me the most about this camera is the automatic exposure. It supposedly has exposure compensation through the menu, but it doesn't function correctly. Maybe I just don't und...

Re: Lang-Elektronik motorized stage

I'm not sure if the micro switches are functional or not, but for the x axis, pressing "start" just moves the stage in the direction of the lighted x axis button. It will move until it hits the end of the rack with motors still spinning or until the "stop" button is pressed. I have done several exp...

Re: Lang-Elektronik motorized stage

I am trying to guess. The stage motion must be controlled by reference to a pre-defined "zero" starting point. A "reset" position. Possibly, pressing the start button sends it to this reference position. If that is correct, then pressing "start " after the stage has been moved with the joystick to ...

Re: Lang-Elektronik motorized stage

I can imagine that this stage has been sold over a microscope manufacturer. Maybe you can find information after you have found out for which microscope it was made? Good idea, but I feel like I have exhausted all information avenues. I'm not sure where to go next. It does fit my Nikon TMD, but I d...

Re: Lang-Elektronik motorized stage

I should say that for my uses, the joystick works just fine. I do a lot of scanning and this makes it so much easier than reaching back and turning those knobs. I'm happy to have this and hope it can last a bit longer.

Re: Lang-Elektronik motorized stage

From experience with other stages: likely the stage has two photo-cell sensor microswitches that mark the ranges of motion, X direction and Y direction respectively. It is important to install them in the exact original positions. Thank you ! There are several switches like the one in the photo 1. ...

Re: Rotifer (Squatinella mutica?)

The technique works really well and the capillary pipettes don't require any manipulation...

Re: thinking out loud here - moral thoughts

I make every effort I can to minimize the harm I may cause the organisms that I observe and culture. Why ? Because I care.

The samples certainly dried out much faster with the 100W , but I honestly cant say that I saw any creatures being harmed by it, I just figured that they were.

I have put Nanodyne LED units on both of the scopes I've used (Olympus BHS/BH2 DIC and Nikon TMD DIC 100W ). Both scopes came with 100W halogen. In both cases the LED was substantially brighter. I mainly went with LED to avoid heating up organisms, so I was less concerned with the photographic aspec...
