    Abstract: An autoclavable diagnostic ophthalmic lens system includes a biconvex lens element having front and rear surfaces and a housing in which the biconvex lens element is mounted. The biconvex lens element is fabricated from a glass having an index-of-refraction greater of 1.7 or greater. The glass composition meets the following parameters: (% SiO2 (by weight)+% B2O3) is less than 50%; % of alkali metal compounds+% of alkaline earth metal compounds is less than 10%; and (% SiO2+% B2O3)/(% rare earth compounds) is less than 1.

    Abstract: An ecology bug catcher for efficiently trapping a bug without killing it includes a hollow tube with a first end and a second end, a catching mechanism for catching a bug, an ejecting mechanism and a triggering mechanism. The catching mechanism has a first position in which it is resiliently biased so that it is normally closed and a second position in which it is held open. The catching mechanism is slidably coupled into the hollow tube at the first end so that the hollow tube holds it in the second position until the catching mechanism is ejected from the hollow tube and returns to the first position. The ejecting mechanism ejects the catching mechanism from the hollow tube. The triggering mechanism releases the catching mechanism. The ejecting mechanism includes a plug, a spring and a connector and ejects the catching mechanism in order to catch a bug. The plug is mechanically coupled to the hollow tube adjacent to the second end. The spring with a first end and a second end is insertedly coupled into the hollow tube. The first end of the spring is mechanically coupled to the plug. The connector with a first end and a second end connects the first end of the spring to the plug and the second end of the spring to the catching mechanism. The connector is insertedly coupled into the hollow tube. A stopping mechanism stops the connector from being completely ejected from the hollow tube.
