                                                                                                                                                                                  休斯敦大學電氣與計算機工程副教授石為川(音譯)說,這種鏡頭能像顯微鏡一樣工作,成本低,使用方便,因此非常適合用在中小學生教室里。它還可用在臨床上,讓那些小型偏遠的診所也能與其他地方的專家共享圖像。

                                                                                                                                                                                  據每日科學網報道,這種鏡頭用聚二甲硅氧烷(PDMS)制成。PDMS是一種濃度像蜂蜜的材料,能精確附著在一個預熱表面逐漸凝固。論文第一作者、博士生宋宇龍說,鏡頭的曲率,也就是放大率取決于PDMS的加熱時間和加熱溫度。最后形成的鏡頭柔韌靈活,就像柔軟的隱形眼鏡,但它們更厚,也略小一些。這種鏡頭可以簡單地貼到智能手機的攝像頭上,即可把攝像頭變成顯微鏡,光學放大120倍后,圖像分辨率能達到1微米。而且,由于PDMS和玻璃并不會永久性地粘在一起,用過后鏡頭還可以很容易地取下來。

                                                                                                                                                                                  傳統鏡頭是通過機械拋光或注射成型制成的,材料一般是玻璃或塑料。雖然也有液體鏡頭,但不能凝固,要裝在特殊容器里保持穩定。宋宇龍說,其他液體鏡頭需要附加設備才能貼在智能手機上,這種鏡頭能直接貼上去而不會掉下來,還能重復使用。對于研究來說,要拍攝人類皮膚毛囊組織的幻燈片,就可以用智能手機-PDMS系統或奧林巴斯IX-70顯微鏡。在放大120倍時,智能手機鏡頭比得上奧林巴斯100倍顯微鏡,有軟件支持的數字放大還能進一步提高。

                                                                                                                                                                                  研究人員估計,造一個這種鏡頭總成本可能是3美分。相比之下,傳統科研用顯微鏡則要花上萬美元。因而,這種鏡頭很適宜中小學生使用,是他們進行田間或室內研究的一種廉價、便利的手段。他們只需把鏡頭貼在智能手機上,就能通過電子郵件或文檔很容易地共享照片,而且由于這種鏡頭非常便宜,丟了或壞了也不是大事。
