LED and Si-based sensor chip maker Opto Tech has raised quotes for all product lines by 10-30%, with orders received since the beginning of 2021 subject to new pricing, according to company president David Huang.

The price adjustments reflect rising material cost, Huang said. Considering long-term relationships with clients and price competition from fellow makers, Opto Tech will not further hike prices in second-quarter 2021, Huang noted.

Opto Tech has been shifting production focus from LEDs to Si-based sensor chips. Currently, the revenue proportion for sensor chips has risen to 60-70%, while LED's has slipped to 20-30%, Huang said, adding LED devices and system products remain at about 10%.

Opto Tech's sensor chips are being certified for VCSEL used in smart home appliances, with shipments likely to begin in second-half 2021, Huang said.

Opto Tech in 2020 became the largest supplier of green-light LEDs in wavelength of 850nm for use in SpO2 (pulse oximetry) sensors of Apple Watch, according to industry sources.

Opto Tech plans to develop cutting-edge technologies, such as LEDs in wavelength of 1,000nm and advanced VCSEL used to measure blood glucose and platelet, Huang noted.

Opto Tech plans to issue new shares for subscription by Japan-based Nichia in a bid to transfer cutting-edge technologies from Nichia, Huang indicated. Nichia currently holds an about 12% stake in Opto Tech.

Opto Tech posted consolidated revenues of NT$5.590 billion (US$196 million), gross margin of 29.40%, operating profit of NT$689.1 million and net profit of NT$575.1 million for 2020, and will distribute a cash dividend per share of NT$1.39 for the year.

Opto Tech has reported consolidated revenues of NT$439.8 million for February, decreasing 27.76% sequentially but increasing 27.25% on year, and those of NT$1.049 billion for January-February grew 39.78% on year.
