Digital Interactive Microscopy Lab Specifications

1. System composition

• Student station: digital biological or stereo microscope, digital camera and student software

• Teacher station: trinocular microscope, high definition camera and teacher control software

• Network: gigabit switches, server or host, cabling

• Display: projector or large screen at the teacher station, computers or all-in-one units for students

• Ancillary: student benches, laboratory tables, uninterruptible power

2. Student station: the key item

• Microscope: infinity optics with plan achromat objectives 4X, 10X, 40X, 100X

• Camera: 5 megapixels or more, USB 3.0, live frame rate of 25 fps or more

• Student computer: i5 or better, 8 GB memory, solid state drive, gigabit port

• Student software: local preview, capture, recording, electronic hand-raising, receiving broadcast

3. Teacher station

• Teacher microscope: trinocular, allowing simultaneous viewing and capture

• Teacher camera: 12 megapixels or more, for both stills and live images

• Teacher software: broadcast, monitoring, grouping, remote guidance, on-screen annotation

• One-click broadcast and switching between student views, with latency of 1 second or less

4. Network and image transmission

• Gigabit switches with backplane bandwidth for all stations streaming at once

• Stream of 20 Mbps or less per station at 1080P, so 48 stations need dedicated bandwidth planning

• Multicast support, avoiding duplicated bandwidth when the teacher broadcasts

• Student stations keep local preview if the network drops, so the class continues

5. Teaching software functions

• Broadcast of the teacher view to every student screen

• Real-time monitoring of any student field, with rotation between stations

• Group discussion, pushing a selected student view to a selected group

• Electronic hand-raising and voice intercom as an option

• Capture of student images and recording of short lessons

• In-class quizzes, answer statistics and attendance records

• Campus network and academic system integration as an option

6. Workstation count and layout

• Standard configuration of 30 to 48 student stations, plus the teacher station and a spare

• Bench width of 1200 mm or more per station, so microscope and computer sit side by side

• Independent power and network points per station, with cabling in under-bench trunking

• Two spare stations recommended for quick substitution on failure

7. Installation and acceptance

• On-site installation: microscope positioning, camera integration, network commissioning, software deployment

• System integration test: all stations powered at once, checking broadcast, monitoring and recording stability

• Teacher training: at least one on-site session covering routine use and basic troubleshooting

• Acceptance: at least 30 minutes at full load with no disconnection, no stutter and clear images

8. Power and environment

• Power supply AC 220 V, 50 Hz, UPS recommended

• Operating temperature 5 to 40 degrees Celsius, relative humidity up to 80 percent

• Blackout curtains recommended, ambient light affects microscopy

• Anti-static flooring and a separately earthed network cabinet

9. Three points where procurement often goes wrong

• Camera resolution or frame rate too low, so student images stutter and smear and the class cannot proceed

• Software assembled from parts, with unstable broadcast and monitoring dropping out several times in one lesson

• Acceptance limited to switching on, without a full-load test, so problems only appear in a real class
