Gmail Notifier

Programs / 2010/03/07 10:31
The Gmail Notifier is an application that alerts you when you have new Gmail messages. It displays an icon in your system tray to let you know if you have unread Gmail messages, and shows you their subjects, senders and snippets, all without your having to open a web browser.

The Notifier is in beta. Before you download it, we encourage you to review the system requirements and privacy information.

If you have the Google Talk client installed, you will automatically receive new mail notifications from Google Talk and you do not need to install the Notifier.

Quarter Waveplate

Physics / 2010/03/02 21:02
Quarter waveplate are used to turn plane-polarized light into circularly polarized light and vice versa. To do this, we must orient the wave plate so that equal amounts of fast and slow waves are excited. We may do this by orienting an incident plane-polarized wave at 45 to the fast (or slow) axis, as shown in Figure 2. When a l/4 plate is double passed, i.e., by mirror reflection, it acts as a l/2 plate and rotates the plane of polarization to a certain angle, i.e., 90.   This scheme is widely used in isolators, Q-switches, etc.

The thickness of the quarter waveplate is such that the phase difference is 1/4 wavelength (l/4, Zero order) or certain multiple of 1/4-wavelength [(2n+1)l/4, multiple order].
Red Optronics provides standard waveplate with  wavelengths (nm) per following:

355
532
632.8
808
850
980
1064
1310
1480
1550
