When drawing what you see under the microscope, follow the format shown below. It is important to include a figure label and a subject title above the image. The species name (and common name if there is one) and the magnification at which you were viewing the object should be written below the image. All relevant parts of the drawing should be labelled on the right side of the image using straight lines. Lines should not cross. Drawings should be done in pencil, while labels should be in pen or typed. Remember that total magnification is determined by multiplying the ocular x objective.

532nm, 200mW DPSS Laser Module Overview These high stability, compact 532nm DPSS green lasers deliver up to 200 mW of low noise output power with narrow spectral line-width. These modules are designed for demanding applications that require both high stability and excellent beam quality. They offer user adjustable output power, a USB interface (RS232 optional) and control software. The standard model is 200mW; other maximum output powers from 75 mW up to to 200 mW (refer the data sheet attached). Small Footprint for Integration into OEM Product or into your R&D Laboratory Set-Up The design and small footprint are optimized to provide easy integration into OEM systems or into a lab R&D set-up. The PowerBox power supply module connects directly into the back of the laser head through a d-Sub connector, and is included in the purchase price. Simple Set-Up and Complete Control using Graphical User Interface / Ltune Software All operating parameters can be set, monitored and controlled from your PC using the Ltune laser control software for Windows. A simple to use graphical interface allows you to adjust the laser power, the temperature and all configuration parameters. Alternatively, the laser can easily be controlled from your own application software. Please request the Operating Manual for a detailed description of the communication protocol. High Stability through Precision TEC Based Temperature Control and Low Noise Control Electronics The active temperature control loop ensures very high short and long term stability, and careful component selection and low noise control electronics enable a low noise laser output.

The depth of focus is greatest on the lowest power objective. Each time you switch to a higher power, the depth of focus is reduced. Therefore a smaller part of the specimen is in focus at higher power. Again, this makes it easier to find an object on low power, and then switch to higher power after it is in focus. A common exercise to demonstrate depth of focus involves laying three different colored threads one on top of the other. As the observer focuses down, first the top thread comes into focus, then the middle one, and finally the bottom one. On higer power objectives one may go out of focus as another comes into focus.

The field of view is largest on the lowest power objective. When you switch to a higher power, the field of view closes in towards the center. You will see more of an object on low power. Therefore, it is best to find an object on low power, center it, and then switch to the next higher power and repeat.
