A microscope camera views a small glass smoke chamber. A laser illuminates the smoke. ASU copyright The smoke filled tube is mounted on a microscope lens with an expansion tube which is mounted on a camera. ASU copyright A close up of the smoke chamber. ASU copyright The heat from your fingers will make the smoke particles agitate faster. ASU copyright A wood match is lit and burns half way before being blown out. The smoke is collected in the tube and a small piece of tape seals the tube. ASU copyright

Description: A smoke filled glass tube is viewed with a microscopic camera. |
||||
| Room:PS F175 | Location: Be2 | Sublocation: | ||
| Type: demo | Date Added:12/8/2000 | Condition: | ||
| Quantity:1 | Complete: | Last updated: 8/24/2006 | ||
| Purpose: | ||||
| Safety Issues: Be sure to backstop the laser. The glass tube acts as a line generator and spreads the beam out. Disclaimer (Warning - work in progress - may be incomplete) | ||||
| Equipment Issues: Objective lens does get a smoke film. Remove the silver lens “shroud” and clean the lens after use. | ||||
| Parts:
Camera – Watec LCL-903K held with rod-mounted Panavise knuckle (0 - 3) Lens – 5x microscope objective with Edmund DIN objective to C-mount adapter & full length extension tube. (O-3) Laser – laser level in spot mode on dual lab jacks Smoke cell – 6mm O.D. glass tubing x 25mm long inserted in rubber grommet for support and taped with electrical tape directly to end of microscope objective to hold & seal it at base. Small piece of electrical tape covers open end of tube to seal that end. Be sure it is well pressed down. wood matches |
